Well - I'll keep this quick. I'm 24, and I've only had sex with one person (my wife). We started having sex about 3 months ago. I'm 100% that she hasn't been sleeping around with anyone else. Before her, my last sexual encounter was over 4 years ago (not sex, but other things). I have had no symptoms up until Monday. On Monday, my wife noticed a single, small, white bump on the bottom of the head of my penis. It is on the head, but near the shaft. Immediately, I thought the worst and thought STD. With more research, it sounds like it could be PPP as well? It seems as if PPP comes in strings, however. I only have one single bump. It's not painful, hasn't popped. Obviously I plan on seeing a doctor - but I'd just like some initial thoughts. If it is HPV/Genital Warts - what are the chances I got it 4 (or more) years ago, and carried it unknowingly all this time - only to now show a symptom? Thanks in advance!
