The skin surface on my penis head is not smooth. It has been like that ever since i can remember. As I have gotten older it has gotten worse. it almost looks like my skin is craking apart. I went to a doctor about 5 years ago and he wasn't sure what is was and prescibed me Aldara. The skin smoothed out, but it went back to normal very quickly after I stopped using it. Does anyone have any Idea what this could be?
