(I try to get rid of the sick fetish which got me into this situation. I know it was stupid beyond believe.)
What I did:
I had sex with a known bareback prostitute at first with condom, last 3 minutes without condom vaginal and anal with ejaculation. Afterwards I washed my penis in the shower.
I wet shaved my genital area including shaft about 1-2 days before. I'm not circumsized.
What happend:
A few days after (maybe 1 or 2) I got two pimples on my shaft. Both 1-2 mm. The lower one disappeared after a week. The higher one is there for 2 months now. It doesnt look like an ulcer and its dry. It was less after first month, but then became more red after a blowjob (because of suction). Today it was slightly white at the top. I popped it. Its like a classic pimple. But for 2 months? Could it be a weird syphilis sore? Or sth else?
