STI Risks: Genital Warts and Herpes After Friction - Urology

Sexually transmitted infections (STIs), genital warts, herpes?


Hello doctor, I would like to ask, two days ago I foolishly went to an adult entertainment venue.
I did not engage in any sexual intercourse, but there was some genital rubbing over clothing; I was wearing underwear and athletic shorts, while the woman was also in underwear, which seemed to have an additional layer of paper padding in the genital area.
We rubbed against each other for about 5 to 10 minutes.
I did not ejaculate, but I noticed some bodily fluid (I found a small wet stain on my underwear after removing it).
As for whether the other person had any secretions, I am not sure.
I would like to know what the chances are of contracting genital warts and herpes in this situation.
What would be the worst-case scenario? Thank you.

Hello: If there are underwear and outer pants, the risk of sexually transmitted infections (STIs) should be low.
● Low-risk sexual behaviors include: mutual masturbation, mutual rubbing, deep kissing, bondage, protected deep foreplay, oral sex with condoms or dental dams, anal intercourse, and vaginal intercourse.
● Moderate-risk sexual behaviors include: withdrawal method (pulling out), sharing sex toys, unprotected deep foreplay, oral sex before ejaculation, and oral sex during menstruation.
● High-risk sexual behaviors include: unprotected anal intercourse, unprotected vaginal intercourse, oral sex during menstruation, retaining semen in the mouth, sharing needles, syringes, and bleeding during sexual activity.

When it comes to understanding the risks of sexually transmitted infections (STIs) such as genital warts (caused by the human papillomavirus, or HPV) and herpes simplex virus (HSV), it's important to consider the specifics of your situation. Based on your description, you engaged in a form of sexual activity that involved friction between your bodies while both of you were clothed. Here’s a breakdown of the potential risks involved:
1. Transmission of STIs: Genital warts and herpes are primarily transmitted through direct skin-to-skin contact, particularly in the genital area. While the risk of transmission is significantly lower when both parties are clothed, it is not entirely absent. If the skin or mucous membranes come into contact with infected areas, there is a possibility of transmission.
2. Friction and Body Fluids: You mentioned that there was some moisture on your underwear, which could indicate the presence of bodily fluids. If either you or the other person had an active infection, there is a theoretical risk of transmission, although it is considerably reduced compared to unprotected sexual intercourse. The presence of a barrier (like clothing) can help mitigate this risk.

3. Risk Assessment: The likelihood of contracting genital warts or herpes from the scenario you described is relatively low, especially since there was no direct contact with the genital area and no penetration. However, it is not zero. The risk is influenced by several factors, including the presence of any cuts or abrasions on your skin, the viral load of the infected partner, and their overall health.

4. Symptoms and Testing: If you start to notice any symptoms such as sores, blisters, or unusual growths in the genital area, it is crucial to seek medical attention promptly. Testing for STIs can provide peace of mind and help in early detection and treatment if necessary. Many STIs can be asymptomatic, so even if you feel fine, it’s wise to get tested if you have concerns.

5. Worst-case Scenario: The worst-case scenario would involve contracting an STI, which could lead to complications if left untreated. Genital warts can cause discomfort and may require treatment, while herpes can lead to recurrent outbreaks and may require antiviral medications to manage symptoms. Both conditions can also have implications for future sexual partners, so it’s important to be aware of your status.

6. Preventive Measures: Moving forward, consider using protection such as condoms or dental dams during sexual activities to reduce the risk of STI transmission. Regular STI screenings are also advisable, especially if you have multiple partners or engage in activities that may increase your risk.

In summary, while the risk of contracting genital warts or herpes from your described encounter is low, it is not entirely absent. Monitoring for symptoms and consulting with a healthcare provider for testing and advice is a prudent approach. Remember that open communication with sexual partners about STI status and safe practices is key to maintaining sexual health.

Hello: If the other person has warts, there is a small risk of transmission through skin contact, even if the duration is brief. As for syphilis and HIV, since they are primarily transmitted through sexual intercourse, the chances are very low. Wishing you good health.
