A week ago I had rough, unprotected sex, with a colleague. We were at it most of the night and several time. The next day there was discomfort, I was sore and figured it to be a friction rash, something similar happed when I was younger from masturbating to hard... Today I noticed that the foreskin felt tight, and its swollen to the point that I can't expose the head of my penis, also it hurt to urinate, it actually felt as if I had been cut, like running my penis along a blade!! I also noticed a... Discharge I think, it was like lint or something. It reminded me of when I was young, I learned the hard way about cleaning beneath the head, there was a build up that caused a tear. The "lint" kind of looked like that... Is this something serious, or am I over reacting?
