Hello.. I'm a male...I had a couple small abrasions at the base of the head of my penis from masturbation. Due to no lube. Couple days later they had not completely healed, I had been checking. I was given a brief bj, by a csw. I brought along a condom and pretty much certain that at least half of my penis (the head and where the abrasion was at the base of the head) was covered the entire time. I put it on and rolled it down and checked part way through, and took it off.. But now Im a little freaked out, like what if.......If it wasn't covered.. do I have a risk of hiv?
