I showed it to my family doctor and she gave me Foskina (
Mupirocin Betamethasone Dipropionate). I also tested negative
for syphilis blood test. I haven't had sex for more than a year (14 months), so I was wondering what could this be? I have been masturbating frequently, reusing a handkerchief to wipe my semen off, i mentioned that cause the day after, a lump appeared and flaked off and reappeared as an "ulcer" after a week.
