I went to a gay sauna, and the following behaviors made me feel scared, so I took post-exposure prophylaxis (PEP) around 22 hours later:
1. I wrapped my lower body in a towel and simulated sexual positions with a man (regard me as top), hugging and rubbing against him for about 2 minutes. Then, feeling unsafe, I put on a condom and rubbed against the man's back for about 5 minutes, with a towel wrapped around my waist. My genitals did not actually penetrate the other person's anus. However, when I went to take a shower later, I used the same towel to wipe my body, and I suspect that the towel may have come into contact with the fluid from the the person's anus, which could have touched my anus. Because I have an anal fissure, I am very afraid of infection.
2. The second behavior is that because I have an anal fissure, I suspect that there may be someone else's semen on the chair I sat on. Could this be transmitted to me?
3. I also briefly licked a man's scrotum and the base of his penis for less than 5 seconds. My mouth did not touch the other person's glans or foreskin.
4. A stranger briefly inserted his finger into my anus, but I immediately stopped him. I'm worried he has semen on his fingers and I have a slit in my anus.
I did not engage in any penetrative sexual activity (both active and passive), but what I am most afraid of is the risk associated with my anal fissure.
I was very scared. Even after taking PEP, I didn’t dare to get tested. I was afraid to face it. Please kind-hearted experts help me analyze the risks.
