So I really haven't had many risky sexual accounters in my time, however about 8-9 months ago now, I had a one night stand. Literally for no more than 10-15 seconds, she performed oral on me. We then had protected sex, so this 15 second time frame of oral sex is the only risky behavior I've had in the last year. Some time after that, I got a bump near the base of my penis, in the area where some hair still grows (i pull out some of those hairs to clean things up) well, the bump looked like a pimple or something of that sort. Eventually, I did notice that a small hair was coming out of it, which led me to believe it was a simple ingrown hair. I had no symptoms such as fever, itching, or anything like that to further worry me that it could be something more serious. (herpes) I plucked the hair with tweezers and the bump went away. There might have been a very small bump remaining, but it went down so much that I didn't even notice it. However, on the 4th, I was out in a boat all day in a bathing suit, which may have rubbed down there the wrong way, but later that night I realized that a bump in that exact same spot reappeared. Similar to before, it resembled a pimple, but there wasn't any hair this time so it doesn't seem like an ingrown hair to me. Anyway, 6 days later now it appears to be almost gone. I'm just worried because a bump popped up in the exact same spot as before. Before the bump popped, it was a little sensitive, but I haven't experienced any itching, fevery feelings, burning, or anything like that. What do you guys think?
