You have posted on the wrong site. Questions about HIV belong on the HIV prevention site. I will do my best to answer your questions with this reply but, if you have additional questions or follow-up they must be on the HIV Prevention site. Sorry
Actually, you should be asking question about infections other than oral sex anyway. The chafing you experienced will make you susceptible to infection with oral bacteria Should your penis start to get inflamed and have increasing tenderness to the touch, you should seek care and antibiotics. There are more bacteria present in the mouth than anywhere else on the body.
As for your HIV risk, in my opinion, you can forget about it. Unless your partner was an IV drug user, the chance that she has HIV is less than 1 in a thousand. If she had HIV, the quoted figure for HIV risk, if one has oral sex with an infected partner is less than 1 in 10,000 and, in my estimation that is too high. Some experts state there is no risk at all from oral sex. Neither of us on this site have ever seen or reading the medical literature of a convincing instance in which HIV was passed by oral sex. That you penis was chaffed does not change this. Thus statistically it is far more likely that you will get hit by lightening than that you got HIV from this exposure. I WOULD NOT suggest PEP.

I'm sorry for posting on the wrong site. Perhaps this message can be moved to the correct area so other people could benefit from it?
Also, I would say that my penis was more than chafed - the skin came off from the high friction. I think what you're saying, regardless of broken skin, is that a one time chance with a woman who gives oral sex is statistically minute to the point of being practically irrelevant. Correct? If so, thank you.
No need to move this, your questin is answered. End of discussion. EWH
