Last Labor Day weekend I had protected sex with a stripper I've known a while. We went at it for about a half hour finishing with her on top. Point being I'm sure there was quite a bit of skin to skin contact. About exactly 5 weeks later I got what looked like a pimple or ingrown hair on my upper pubic region. It really didn't look like a blister because it was hard to the touch but who knows. I shrugged it off and it went away. About a month ago it reappeared and this time it took longer to go away and it left behind a little patch of red skin that is still there. I'm just wondering what you think. I've been screened for the other stis and come out ok.
