So I'm 16. Haven't had intercourse yet however I was asked by a "special friend" to shave so that we could. I had shaved a few times before this but never had anything like this. I seem to have a rather large pimple maybe 4mm? I read some of the other threads that got replies that this was common and saw a link of something like this sort of but in the description pic it was a bunch, at least 30+ really tiny white headed pimple type things on the penis. Mine is 1 rather large white headed one on my scrotom. I'm ruling out most STDs and assuming this is normal. Confirm/deny? I've been putting baby powder on it. Help would be appreciated
