I'm a 26 year old sexually active male. Last fall I had unprotected sex with a girl I didn't know, and once with a fairly shady girl but I used a condom. I've been with another girl since, but she has no symptoms of anything. My first concern came about two months ago when I found a couple small red bumps on the underside of my penis shaft, with a tiny one on the head (haven't had one on the head since). But ever since, the small bumps come and go every couple days, on the bottom side of the penis shaft (never on the top). They're small, don't hurt, don't itch... just little red bumps, slightly raised, like pimples. Under friction (masturbation or sex), they may get a little more irritated, but are never bigger than a centimeter. If I masturbate too vigorously, they can open, but still won't hur, and they'll scab over and go away, similar to a popped pimple. Again, never hurt or itch. I also have had a couple around my navel. I was told by a friend who's a sex therapist that they don't fit the description of any STD, but they won't stop coming and it scares me. I've never been much for showering (my whole life). I'm not a smelly person at all so I only shower once a week or so. Upon her advice, I started showering everyday (and changing my boxers, which I never did much either) but it doesn't seem to change. Without friction they go away or are very insignificant. But even with friction they'll scab over and go away. I'm holding off on getting tested due to the money and medical record, but they just won't go away... they don't even bother me except the stigma of thinking I have some freak version of herpes or HPV. Any ideas?
