Okay, I first asked this question in the STD forums, but it quickly fell to "it's not Herpes" which was not quite what I was originally asking. I have what appears to me to be a pimple on the upper part of my penile shaft on the shaft skin. I first noticed it while masterbating, after which it grew from a very small, single lesion (>1mm) to a larger (maybe 2mm) light red lump. It's not painful really, unless I irritate it. I have looked at it under a strong magnifying glass and there appears to be a head to the bump which looks either white or clear, it's too small to tell. I've tried to pop it but haven't been able to.
I'm not thinking it's an STD, I had a risky exposure 9 months ago, after which I've had no STD symptoms and had undergone a large number of tests, all of which came back negative (including a negative HSV IgG test at 18 weeks).
I've been putting a 10% benzoyl peroxide cream on it for 2 days but haven't noticed any reduction in the spot.
Obviously pimples can happen anywhere on the body, but so high up on the penile shaft, so far from hair seems really weird to me and not normal (especially since I have no history of pimples like this). I'm also in a situation where I can't go see a provider for the next couple weeks.
So this is where the forum comes in, I'm looking to either here that this is in fact normal and to chill out, or to keep an eye out for these follow on symptoms, or it sounds like this instead of a pimple, or whatever.
Thanks.
