last night I had sex with a girl. Today I have been feeling a uncomfortable itchy feeling on my penis when i walk or it touches anything. I got back to my dorm room and looked at it. The head has little red dots, like pin size. and the part around the bottom of the head is irritated and red and itchy when touched as well. I don't know the technical term or even slang for that part but it is the part that gives it it's shape. I am circumcised and do not have a weird penis. but this is really freaking me out because I don't really have a lot of sex and I finally decided to just do it like all my friends and now i think i may have something. there is no discharge, no burning when i pee, no puss or anything just little dots and itching.
