the foreskin of my uncircumcised penis kept rubbing against my testicles and caused a red irritation. i started to put keep my penis through the hole of my underwear to avoid the friction which seemed to work, however the foreskin still seems to be getting red and irritated on its own. its always the left side of my penis (which is the side my penis hangs), the foreskin gets bunched up. After a day of work when i pull it back its moist and red. after i take a shower it goes away. it doesnt itch or hurt, just looks unpleasant. i was in a relationship for 3 years, im recently single and just want to know what this could be and how can i prevent it for good
