I have what seems to be a rash on my scrotum that does not itch,and also some small pinkish bumps on the underside of my shaft kind of in the area of skin that is not smooth where I was circumcised,I had my doctor look at it and he said it was normal because of my irritated rectum from being constipation.I masturbate sometimes twice a day,and have sex every other day,could this be from masturbating too much,just looking to see if anyone has this problem or can help.
