I've had sex with this girl maybe a week ago. The first part was unprotected but the second round we had was protected. I did experience any symptoms till about 3 days after me and her had sexual intercourse. My balls are red and look irritated, they do not itch but when I do itch them it feels good. Also the pee hole of my penis looks to be a bit red like it's burned??? I can touch it on the right side but when I touch it on the left side it gives this stinging pain. Please help, I'm too embarrassed to go to a doctor about this.. I might go on Friday.
