what is on my penis after we have sex?
after me and my girlfriend had sex a couple times there was like this crust on my penis, its like flakey skin or somthing. its weird and ive never seen it before. it kinda reminds me of waking up in the morning after having a wet dream and how theres all the flakey dry semen stuck to your penis. what is this? its not a STD or anything is it?
