My situation is that I was the top engaging in homosexual sex, and upon pulling out I noticed that my penis was only covered about 2/3 of the way. The condom looked like there was a fold at the base. I am wondering if rectal fluid could have entered the condom this way, thus making me vulnerable to HIV? Worried because I did trim the pubic region, and there may have been a razor cut on the base that could have been open, and giving an entry way for the virus? I did rub my unprotected head on the opening of the anus prior to engaging in intercourse, and I am assuming that this act in itself is not a risk, but out of curiosity, and for the sake of validity, would this be considered a risk as well?
Thank You!
