I've been dealing with this bump on the rim of my penis for about 7-9 months and it's driving me crazy. It appeared about a week or two after unprotected oral sex from a girl from I met at a sports bar but I I didn't think anything of it so after a few weeks it didn't go away so now I'm freaking out, so I grab some peroxide and drown it. It's didn't do anything so I squeezed it and a strand of white came out so I put peroxide on it again and it fizzed up white. So next I hop in the shower and I scrubbed it raw basically to where I took it off myself. Then it started to scab but has been stuck like that for a couple of months and I've been to the er for it twice and had urinalysis done along with a swab of the scab/bump which came back negative. Then 2 months later I returned to same er which did a std panel except for herpes/hpv because of the negative swab. Another urinalysis and std panel negative after having the bump scab for 6 months. Followed up with a urologist who checked out my equipment and urinalysis (conducted by him) and said I was fine but I forgot to tell him about the scab but being my stuff was out he should have seen it right but you have to really look to see it. So next would be a dermatologist which I went to see and I showed him the spot and he said it's probably irritation and prescribed hydro valerate for two weeks and come back in three which I schedule before leaving his office but it's been healing and I keep peeling it bit by bit. Is it infected or some std? Do herpes or some other std cause a single scab on the rim of the penis? Do I have to live with the scab/scar because I can't have sex with this on my penis head. I've been masterbating like a mad man could this be stopping the healing. I need help!!!!
