After sex, my penis is swelling two to four days before its cool down. I don't understand. Yes, I had an unprotected sex. Anyone can help?

are you possibly having too rough sex? you did not mention if you were having intercourse or masturbating?

1. You need to have a sexual infection checkup just to make sure.

2. I think you need to use lots of lubricant as it sounds like you are getting a friction injury!
