Hello, I sometimes develop an odd rash on my penis. Ive only had it three times ever. Twice on my Penis head and once on the skin just below the head, where the foreskin was removed. It seems to happen when i masturbate frequently with lotion but im still worried its something else. There arent any blisters, but the skin is red and dry. only slight itching sometimes. it seems to be worse when i masturbate without lotion. During the day it mostly goes away, but if i masturbate it will get very dry and cracked and flaky. What could this be?
