I have small reddish blisters in my penis head that goes away after 2-4 days after intercourse and comes back after i have intercourse. Sometimes it's not blister but look like my skin get scratch up. It just start to happen 3 months since I start to notice my penis head skin was pealing. Help please.
One differential for your case is a balanitis which may be secondary to a fungal , bacterial or viral infection.
Does the rash itch or is it painful?
This may not be something very urgent.It may be that the area has been irritated or mildly injured during sexual activity.It is best however,to have this assessed by a urologist.Refrain from any sexual activity for the moment until this has been thoroughly assessed. A dermatitis may also be a differential.
