I need to see if anyone knows what if anything is wrong. The top side head of my penis is a different than my foreskin and shaft. It is a light grayish color with red spots. The underside right at the frenulum is the same color and always feels a little scab like. Anyone know what could cause this and how to fix it? I am embarrassed to get a blow job and that is one of the reasons I have never been the giver when having sex.
