I am a 28-year old Singapore male citizen and recently had unprotected sex with a prostitute of Chinese ethnicity who told me she was Javanese during my visit to a friend's wedding in Jakarta, Indonesia. This was in the suburbs in one of the "complexes" - one of the more lowly hangout areas for laborers and blue-collarers where it was dark and dirty. The sex was cheap and good - of course because I didn't use a condom! I feel like **** now.
I couldn't give her a "once over" since I had 5 beers to drink that night before the encounter and that impaired my sense of smell. It was dark in the room too so I don't have even the slightest idea if she had any STIs. She told me she was tripping (but didn’t tell me from what) and didn't care if I wanted to use a condom or not so there's a high chance that she goes promiscuously without one. She gave me a blowjob without condom and I later screwed her also without using a condom. I used the withdrawal method and came onto her stomach because I was told before (and this seems to make sense to me) that the penis does an "absorbing" motion during each interval of a spurt during ejaculation. I know I did not withdraw late because I stifled the first spurt and pulled out before allowing it to happen.
This is the second time I have made this mistake. The first time was in Huizhou of China and I was cleared after 3 months and told myself I wouldn't do it again. That was 3 years ago, and I had been using condoms ever since. However, in recent spate, I have begun to become sick of using condoms all the time. That's why I made this second mistake.
I will definitely go for a check up, since this would count as the 3rd or 4th time I've done so. It has been one month since this exposure. I have not experienced anything that is out of order (no swollen lymph nodes, discharges, fatigue, manifestations around the groin area, etc.) at this moment. In the meantime I am really scared so I have decided to write.
Say, SUPPOSING if I were not infected by any STIs, is my risk of HIV infection any different? Really appreciate your help. I was too late in using PEPs.
