hi earlier this week I noticed a shiny red puffy patch on the head of my penis. it's about the size of a pencil eraser. and is not so much painful as it is overly sensitive. it is just above my circumcision scar. it tends to form a slight form of scab if I let it dry out for a couple days. and if I peel the little scab off it doesn't bleed. but is just very red and shiny. the whole little patch is also slightly raised. I've never encounterd this before. I'm pretty sure it's not an std. but probably a rash of some sort. but am wondering what type of cream I could perhaps buy to clear whatever it is up. if need be I could send you a picture.
