Bareback fellatio involves sucking or licking a penis without covering it with a condom. It does not necessarily involve the man climaxing or the person performing the fellatio swallowing the ejaculated semen.
Bareback fellatio does not allow HIV infection. However, it does allow the passage of many pathogens such as the hepatitis B virus, spirochetes responsible for syphilis, gonococci responsible for gonorrhea, chlamydia, and the Toxoplasma parasite. All of these germs are found in semen. You can get vaccinated against hepatitis B.
The person performing a blowjob with no condom takes a greater risk than the person receiving it, because all these pathogens are found in the pre-seminal fluid (a small drop of lubricating fluid that neutralizes the acidity of urine and the vagina: it comes out of the penis when it is erect) or in semen: both of these fluids can be infectious if ingested. Regarding syphilis, since the treponema is able to attach itself to the mucous membranes and actively penetrate them, the person receiving the blowjob takes as much of a risk as the person performing the blowjob.
PrEP is an innovative HIV prevention strategy. It stands for pre-exposure prophylaxis. Prophylaxis = avoiding infection. Pre-exposure = treatment must start before (and continue after) possible contact with HIV. PrEP is for people who do not have HIV, and consists of taking a medication to avoid contamination. PrEP must be prescribed by the checkpoint or SwissPrEPared center nearest you and requires monitoring. It is reimbursed since July 1, 2024 in Switzerland. Find your PrEP center here. For people with an insurance model through a family doctor or telemedicine consultation, a delegation voucher is required.
Currently, the only medication authorized in Switzerland for PrEP is a tablet that combines two antiretrovirals against HIV: emtricitabine and tenofovir disoproxil . This medication was initially marketed under the brand name Truvada® . It is now available in generic versions, produced by different laboratories. PrEP does not protect against other sexually transmitted infections (STIs): gonorrhea, condylomas (linked to the human papillomavirus HPV), chlamydia, hepatitis A (HAV), B (HBV) and C (HCV), syphilis, etc. It also does not prevent unwanted pregnancies. This is why PrEP must be accompanied by reinforced and individualized monitoring of sexual health: vaccinations, regular screening for sexually transmitted infections (STIs), treatment of STIs, pregnancy tests, contraception. Be careful, PrEP works in 2 hours in men, because their anal mucous membranes and their sperm quickly contain the molecules that eventually protect you. In women, PrEP must be taken for seven days: only then will the molecules have had time to penetrate and accumulate in the mucous membranes of the vagina or neovagina, only then will PrEP prove effective.
The FOPH recommends vaccination against hepatitis B and HPV (human papillomavirus). It also recommends vaccination against hepatitis A and MPOX (monkeypox) for high-risk groups such as men who have sex with men (MSM). Talk to your doctor or seek advice from a sexual health center.
The human papillomavirus (HPV) is a widespread virus that infects the skin and mucous membranes. There are many types, each of which can cause a variety of diseases. Some can cause precancerous stages or cancer if the infection persists for a long time. HPV is transmitted during vaginal, oral, or anal sex. But it can also be transmitted through hands, sex toys, or other objects brought into contact with the genitals of multiple people.
Sodomy is a relatively risky practice in that it allows the biological fluid secreted by a potentially infected individual to be deposited on the anal mucous membranes and its capillaries. These are highly permeable and even have the function of absorbing the liquid that would still be present in the stools after digestion. Also, passive sodomy is the riskiest sexual practice and should always be done with a condom in order to avoid classic sexually transmitted infections (HIV, syphilis, hepatitis B, chlamydia, gonorrhea, monkeypox) but also diseases caused by intracellular bacteria such as tuberculosis (Mycobacter) or brucellosis (Brucella) as well as intestinal spirochetosis (Brachyspira) during anal penetration with multiple partners. Active penetration is also a risky practice, especially when the man is not circumcised and the mucous membranes of his foreskin are present and in contact with the vaginal fluid. This foreskin is where most STIs, including HIV, enter. Gonorrhea, on the other hand, settles directly in the urethra.
CMTP is not an escort agency and is therefore not in a position (nor does it want to) force escorts to do anything. Moreover, in Switzerland, no structure can force STI screening. Let’s not forget that sex work in Switzerland is an independent activity within a liberal framework and that escorts are « their own bosses »: it is only under this condition that sex work is accepted and regulated.
Just saying: an escort who agrees to have unprotected sex with you, agrees to do it with others too.
Hepatitis B is an infectious liver disease caused by the virus of the same name. Hepatitis B is transmitted through contact with bodily fluids (especially blood and genital secretions) from infected people, primarily during sexual intercourse. An infected woman can transmit the disease to her child during childbirth. Diagnosis, treatment, and vaccination are available here.
Syphilis is a disease caused by a spirochete. Spirochetes are spiral bacteria that progress through the body, gradually invading all supporting tissues (connective tissues with a high collagen content). In these tendon-like, poorly vascularized tissues, spirochetes are not only protected from blood immunity, which has poor penetration of connective tissue, but they are also well positioned to create low-grade local inflammation and feed on the tissues they degrade around them. It is this degradation of organ structures and nervous tissues that creates, over many years, most of the symptoms. Before the 19th century and the advent of antibiotics (penicillin), people died slowly from syphilis, and the invasion of the nervous system by spirochetes was associated with numerous neurological and neuro- immuno -psychiatric conditions. Syphilis is making a comeback these days, its transmission being catalyzed by the gradual abandonment of condoms by younger generations and by the almost universal adoption of practices such as blowjobs without protection. Indeed, the spirochete is found in the saliva of the infected person or in their semen or vaginal fluid and has no difficulty penetrating the mucous membranes of the people on whom it is deposited. All sexual practices are concerned: French kissing , fellatio, cunnilingus, rimming, vaginal and anal penetration, exchange of dildos. Even massage if the infected person were to present syphilitic spots on the palms of their hands!
Rimming is the stimulation of your partner’s anus with your tongue. The person doing the rimming is especially exposed to enteric infections from the person receiving the rimming: hepatitis A virus, Escherichia coli, Salmonella, Shigella, Brachyspira, Mycobacter, Amoebas, Giardia. Also, any acute or chronic diarrhea after rimming with a new partner should raise the possibility of enteric disease transmission. Any strange abscess that occurs in the liver or brain should also raise the possibility of amoeba transmission. The anal margin is also the breeding ground for many HPV viruses. It is possible to be vaccinated against hepatitis A and nine oncogenic genotypes of HPV (types 6, 11, 16, 18, 31, 33, 45, 52, 58).
Cunnilingus allows the transmission of the following sexually transmitted infections:
The French kiss , or deep kiss with the tongue, is characterized by the exchange of saliva and the exchange of microbiota in the oropharyngeal cavity. Viruses such as herpes, hepatitis B, monkeypox , influenza, Epstein Barr virus (mononucleosis), bacteria such as chlamydia, gonorrhea and syphilis are transmitted. The latter is by far the most problematic.
Mutual masturbation poses only a low risk of STI transmission. In fact, the transmission of an STI usually requires contact between a physiological fluid and a mucous membrane (thin, pink, and moist skin). The skin of the hand, like that of the external genitalia, is essentially dry and keratinized skin. One exception, however, is treponema, the bacterium responsible for syphilis. This bacterium is capable of « drilling » an entrance into keratinized epithelia: this entry point is called a chancre. Syphilis can therefore easily be contracted if a biological fluid (pre-seminal fluid, semen, saliva, female cyprine) comes into contact with the skin.
Some sex workers follow a relatively simple rule: one hand for themselves and one for the client! This way, no one puts genital fluid on the other’s penis and vice versa.
These are viruses present in the feces of infected people. A person becomes infected through the mouth, through contact with unclean or contaminated water or food. These two hepatitises are therefore particularly common in densely populated areas where hygiene, wastewater disposal, or disinfection practices are poor. In our countries, the main risk lies in the sexual practice of anulingus,i.e. mouth-anus contact, which can expose people to HAV and HEV. After an acute, very tiring phase, the body eliminates the virus. Hepatitis A or E never becomes chronic. In some cases, however, hepatitis can be serious. There is no treatment for these two hepatitises, but a vaccine against hepatitis A exists . This vaccine is reimbursed when combined with the hepatitis B vaccine. It is recommended for exposed people such as gay men, people already living with hepatitis B or C, people traveling to endemic areas, or finally people living from sex work.
Vaginal intercourse without a condom with an escort can feel exciting at the time, but can be distressing once the excitement wears off. Often, this leads to regret and the possibility of contracting a disease, especially when you feel guilty.
If you have reasons to believe that the escort in question is HIV positive, you have 24 hours to consult the emergency room in your city to obtain a prescription for a month of HIV Post-Exposure Prophylaxis (PEP).
If the escort had a chancre or told you about an untreated syphilis exposure, you should quickly take a doxyPEP . Another option is to have a syphilis serology test done in the days following the intercourse and then find that you are negative. You can then have a syphilis serology test done again six weeks after the exposure: if it comes back positive, you will need to treat with intramuscular penicillin.
If a few days after the sexual contact, you experience irritation of the urethra and burning when urinating, you should be tested for gonorrhea, and if the test is positive, treated with intramuscular ceftriaxone.
If you develop chronic deep pelvic pain or chronic prostatitis, you should be tested for chlamydia. If positive, you will be treated with oral doxycycline or levofloxacin for seven days. A single oral dose of azithromycin may also be recommended.
Escorts generally protect themselves well and are committed to staying healthy. Also, don’t hesitate to suggest to the escort you took a risk with that they go with you for a screening at your expense the day after sex. Often, they will accept, and you’ll both come away feeling reassured!
The mucous membrane of the mouth is in fact almost like skin, that is to say an epithelium, made up of several layers of very resistant cells. In addition, it is lubricated by saliva which contains numerous molecules that inactivate a large number of viruses. Also, as long as the sperm only remains in the mouth and is then spat out, there appears to be almost no risk of HIV transmission. It should be noted, however, that many sexually transmitted bacteria have cilia (a type of swimming hair) capable of propelling them and attaching them to the epithelia: this allows them to colonize surfaces like the inner mouth and throat (Chlamydiae and Gonococci). Other bacteria are even better equipped and are capable of slowly intruding through the cells and colonizing all connective tissues, such as spirochetes and, more particularly, syphilis. The entry point for syphilis is called a chancre and looks like a flat, even concave, red, and painless lesion. In short, oral sex allows the transmission of most STIs (syphilis, chlamydia, gonorrhea, hepatitis B) but not HIV.
Fingers are covered in bacteria and viruses from the outside world, and one might think that it is these microbes from the outside world that could represent a danger and colonise human orifices (mouth, vagina, anus) into which fingers are inserted. However, this is generally false. Indeed, the mouth, like the vagina and the anus, are places open to the outside world, continually exposed to germs from the great outdoors. They know how to fight against these germs and manage them. However, there is a very real risk of transmitting sexually transmitted infections through fingering. Any finger that has first been exposed to someone else’s bodily fluids (put in an anus or vagina, for example) and is directly introduced into an orifice without being wiped or dried, transfers pathogens from one person to another. The risks are particularly high with bacteria capable of attaching to epithelia such as chlamydia, gonococci and treponemes (syphilis).
Breasts are generally not carriers of STIs. However, it should be noted that milk can convey the HIV virus and, in many poor countries, is the most common route of transmission between a mother and her infant…
Wearing a condom provides good protection against STIs. The only exception is HPV, a virus that can easily be transmitted through contact between pubic hair and the genitals. A crab infestation can also be transmitted with a condom, as these insects live attached to the base of pubic hair.
Since 2022, the monkeypox virus (MPOX) has only resurfaced among men who frequently change sexual partners, or trans women who have sex with men who themselves have numerous male sexual partners. The epidemic has not particularly emerged among cis female escorts , and the public health office therefore does not recommend vaccinations for them or their clients before sex.
A condom left in the body means possible exposure to sexually transmitted infections and the risk of unwanted pregnancy. Therefore, it is important to take the morning-after pill if you are a woman not taking contraception. As for STIs, the first step is to assess your HIV risk. To do this, go to the nearest emergency room within 24 hours. If the risk is high (sexual partner having frequent sex with men or trans women or people from countries with a high HIV prevalence), then post-exposure prophylaxis (PEP) may be indicated. If you think there is a high probability that your partner has chlamydia or syphilis, doxycycline Post Exposure Prophylaxis (doxyPEP) may be considered. If PEP is not indicated, you will need to do a p24 antigen test or HIV viremia test no earlier than six weeks after the risky intercourse. You can then ask for an HIV serology test three months after the risky intercourse to confirm that you are still HIV negative.
A broken condom means possible exposure to sexually transmitted infections and the risk of unwanted pregnancy. Therefore, it’s important to take the morning-after pill if you’re a woman not taking contraception. As for STIs, the first step is to assess your HIV risk. To do this, go to the nearest emergency room within 24 hours. If the risk is high (sexual partner who frequently has sex with men or trans women or people from countries with a high HIV prevalence), then post-exposure prophylaxis (PEP) may be indicated. If you think there is a high probability that your partner has chlamydia or syphilis, doxycycline Post Exposure Prophylaxis (doxyPEP) may be considered. If PEP is not indicated, screening for p24 antigen or HIV viremia should be carried out at the earliest six weeks after the risky relationship, then HIV serology three months after the risky relationship.
When you have unprotected sex while taking HIV PrEP or treatment (TASP, U=U), you won’t transmit or contract HIV. However, you can still transmit or contract infections like syphilis, chlamydia, gonorrhea, hepatitis B, and human papillomavirus. You can get vaccinated against the latter two.
Hand skin is very thick unless it has microcracks. Therefore, it is very rare for STIs to be transmitted through hand exposure to infected fluids. The only possible exception is direct contact of a syphilitic chancre with the skin, as treponemes have the ability to penetrate the skin.
You can only get HIV by coming into direct contact with certain bodily fluids from an HIV-positive person with a detectable viral load. These fluids include semen and pre-seminal fluid, rectal fluids, vaginal fluids, and breast milk. For transmission to occur, the HIV in these fluids must enter the bloodstream of an HIV-negative person through a mucous membrane (located in the rectum, vagina, mouth, or tip of the penis), through open cuts or sores, or by direct injection (using a needle or syringe). HIV-positive people who take prescribed HIV medications and achieve and maintain an undetectable viral load can live long, healthy lives and will not transmit HIV to their HIV-negative partners through sex.
HIV can only be transmitted through specific activities such as:
Receiving a vulva on your face is not in itself a very dangerous practice. However, cunnilingus, which is often associated with this practice, allows the transmission of chlamydia, gonorrhea, and syphilis in rarer cases. Also consider vaccination against hepatitis B. Do not ingest menstrual blood either (hepatitis C, HIV).
Generally speaking, standing in a golden shower (receiving a partner’s urine on your body) does not pose a serious threat to your sexual health. Although your urine is not sterile, the small amount of bacteria it contains is unlikely to transmit any disease. If you want to be even safer, a general rule is to only expose your skin and not allow urine to flow into any orifices. Therefore, do not allow the stream to come into direct contact with your eyes, mouth, vulva, or anus. However, some pathogens specialize in transmission through urine, and always consider leptospirosis if you develop, 5 to 14 days after a golden shower, a high fever with chills, headache, very red eyes, muscle and joint pain, and possibly a cough. Tuberculosis can also be contracted if you inhale/ingest a little Mycobacter -contaminated urine . Mild symptoms of primary tuberculosis infection include low-grade fever, fatigue, cough, and rarely, fleeting chest pain.
Spitting is the exchange of saliva and more specifically the act of spitting on the penis or vulva or anus to facilitate penetration. Spitting also means spitting in one’s partner’s mouth to create a feeling of dominance. The risks of spitting are the transmission of influenza, streptococcus, childhood illnesses (mumps, measles, rubella), SARS-CoV-2 (COVID-19), gastro-enteroviruses (norovirus and rotavirus), tuberculosis, herpes viruses (HSV 1 & 2), mononucleosis (Epstein Barr virus), papillomavirus, cytomegalovirus, hepatitis B, chlamydia, gonorrhea or even syphilis.
HIV is transmitted through vaginal intercourse. Although the epithelial cells of the vagina are not susceptible to infection, the immune cells present in the vaginal wall (macrophages) can be. Once infected, these cells then travel into the bloodstream via the lymphatic system, carrying HIV. It is important to always protect yourself during vaginal intercourse.
Prevention of vaginal over-colonization by Candida (yeast infections) involves several strategies aimed at maintaining a healthy vaginal environment favoring lactobacilli and the acidity they maintain by secreting lactic acid (pH ~3.8). Here are some preventive measures:
Sexually transmitted infections (STIs) can present with a variety of symptoms in men, although many STIs can be asymptomatic, meaning they do not show any signs. Here are some common symptoms associated with STIs in men:
***
Female orgasm, like male orgasm, is accompanied by the secretion of a liquid. This liquid is produced by the paraurethral glands. They are located on both sides of the urethra and ventrally, therefore at the entrance to the vagina. The secreted liquid has a volume that can range from 0.5 to 2 ml and serves mainly to lubricate the entrance to the vagina during the woman’s arousal. It is whitish, made of glycated proteins: it is a natural lubricating gel. Squirting women are not women whose paraurethral glands produce tens of milliliters of gel.
It appears that in some women, during genital stimulation, the kidney produce an odorless and colorless ultrafiltrate. During relaxation of the bladder linked to pleasure and orgasm, this liquid can either flow during sexual stimulation and during orgasm continuously or intermittently … hence the name « squirting women ». Squirting women are therefore not particularly more infectious. On the contrary, the clear liquid emitted has not remained long in the bladder or urethra and carries few germs: this liquid is therefore not very infectious.
