When I pull the skin back from my penis, it s a little bit red on the skin around, underneath the head. it has a leathery feeling... It's normally a little worse after masturbating, and sometimes when I wash it, some small blood spots could appear where it's red sometimes after washing. It doesn't hurt otherwise though Doesn't itch or give any discomfort, when I first got it, the skin would flake off as if it were dead every few days in the shower, but this has stopped.) how could I fix this?
