About 4 weeks ago, I found a single tiny (1 mm) blister on the underside of the shaft, precisely on my circumcision scar offset to the side by maybe a quarter inch. I stupidly popped it, and the resulting fluid was pus; white and thick. The resulting lesion was a was only visible when I stretched the skin out, and otherwise, all I saw was a slightly pink area. I took a shower, patted the area dry, and went about my day. A little after noon, I looked again and the area was less red, and there was no more "shine/glimmer/wetness" to it, even with the skin stretched. The next morning, the redness was basically a faint pink completely gone, and by noon, all that was left was a flesh coloured bump that remains there to this day (month after initial blister). (Note that I have many fleshy bumps/glands/textured rough skin in the same area. I had these areas examined by a dermatologist a few years back, who said they all "might be milia, but definitely not HPV". He didn't sound certain exactly what they were, but didn't seem concerned that a pathogen was involved.) I've also had several cases of folliculitis in my pubic hair, which I don't believe are herpes but perhaps is evidence of staph or strep?

I've been monogamous with the same partner for nearly 2 years now, and though we've had other reproductive health issues, this is the first where herpes feels likely, which has been causing me a lot of (hopefully unnecessary) anxiety. 

Thank you!
