My penis is normal skin colour, along with the left and right hand side of my testicles, I also have a strip of normal coloured skin going down the middle of my two testicles. But either side there is a patch of
darker(slightly redder skin) it's been there for a while now. It's just darker skin with a bit or red in it. I don't find it as sensitive being touch on the darker parts then on the normal parts.
I used to have "itchy balls" about a year ago, but I haven't had that problem in a long time, I got some cream for it, but the doctor only knew it was itchy, unless he saw it. But he gave me some Daktacort cream with miconazole. I never used it.
