I remember back in 10th grade that I could not find a cup that fit me very good. Either my package literally did not fit or the cup shape did not fit my body. I was like 5'8 and 120 back then, I'm 6'1 160 now. So very thin but pretty good muscle build I think. Sometimes Id get inside the cop but after 10 minutes or running and sweating I got uncomfortable. The excerices plus the extreme heat engorged me and I starting coming out the sides. Anyone else have this problem?
