I noticed yesterday that i have a few red bumps right below my penis' head (on the shaft). On the other side of my penis, there is some dry skin and flaking with a few other small red bumps here and there (not as severe). None of it itches, there is no burning, and it doesn't even have pain when they are scratched. I know, I'm not a doctor, but it looks NOTHING like the genital herpes. Is this some kind of fungus or jock itch?

 

Just some notes: Yes, I did have sex with a girl for the first time less than a week ago (no condom). She was on her period, and I didn't shower until morning.
