Hi i’m a young gay guy who never had anal sex only unprotected oral sex and now i’ve noticed a BIG RED with a white or yellow head pimple on my **** the torso of my penis. And i’m wondering if that’s only an oil gland that is clogged or something more serious. i’ve looked at pictures of genital herpes as i usually see bunches of pimples and in my case there is only this BIG one so could i have genital herpes or any other disease? Please help. i can gladly send pics. Please help thank you so much!!!
