Pubic hair can be a problem for men who have had a high circumcision, which means the scar is nearer to the base of the shaft than normal (or further away from the glans). The problem is caused if it results in a lack of skin on the shaft of the penis, thus resulting in the penis "borrowing" skin from the pubic bone region. This subsequently results in a penis that is unusually hairy on the shaft. This makes the penis look smaller. It also makes the penis look really weird, like some sort of hairy monster or something.
