I get a red rash all over my chest when vigourously masturbating, seeing as how I knock one of 6 times a night because I don't know how to talk to any girls and made a vow to eat a bullet if I don't get laid by 21, this happens a lot.After I finish, I notice a huge red area on my chest, it doesn't hurt, and goes away about 10-15 minutes later. What is it?
