As a 21 year old gay male, i had my first sexual experience the other evening with another male who i didnt know very well. He had protected anal sex with me briefly but not long enough to ejaculate and then we performed unprotected oral on eachother; again, no one climaxed or ejaculated semen. But im worried about pre ejaculatory fluids. He said he was clean and was even willing to show paperwork, but i stupidly told him not to worry about it. The condom did not break when he penetrated me but he stupidly used lotion as lube. Like i said though there was no orgasm or ejaculation in this experience. What would you say are my chances of having contracted hiv?
