If I have cellulitis on head of penis ( I think this is what I have....flaky skin, white, flakes off with water, went away for a month...goes away with water, but was slightly swollen... I was worried because I am used to having protected sex and since my girlfriend is pregnant, we have had tons of sex w/o condoms which I've used my whole sex life....anyways, I pick the flaky skin, but the swelling went down, it was painful one of the days, but then went away for a month. it just came back) I am wondering if I should take an antibiotic or if there is a crème, or what course of action I should take to ease this , and not to have it worsen. the swollen area is slight and red and shiny.
