I have had trouble down there for like a month. At first i was paranoid cause i slept with a woman who has had alot of sexual partners, I wore a condom but i had a little bit of unprotected oral(this happened back in feburary). Also i have used lotions with perfumes, and i was using conditioner to wash down there. Any way i have bump on the head on my penis and behind it, They look very irritated. I am not sure if they are pearly whites or gential warts, I went to the hospital and i have been checked for stds but thats all they did was check me and didnt tell me what was wrong but told me they have found blood in my urine and i have signs of a kidney stone.(i came back clean) I have urologist appointment on may 2nd, But i am in alot of pain and i cant even masturbate or erection hurt me. I have no idea why and why would i have a irriration for so long. So i was wondering if kidney stones can have bumps form on your penis or what?
