Is it unusual to not be able to tan the area where the bend is. My entire body tans except for that area and I'm wondering if it's because of the plaque / scar issue under the surface
This makes no sense to me at all. The plaque we refer to is on the Tunica tissue which is part of the structure of your penis. The skin covering your penis is completely different and separate. I don't know why the skin covering the penis would not tan the same as the rest of your body. The glans is a different issue altogether. If you are circumcised I have no idea if the glans would tan or burn first. I would be very cautious of this.
