I had sex with my gf last night and??

i feel a stingy feeling on the tip of my penis, is this normal? I'm only 20?

no, but it might not be anything too major either...it could be the beginnings of a yeast infection or if she had a urinary tract infection starting and you were doing a lot of general area play not just get in get out then you might have caught it too. both a pretty innocent as many times people don't know they have em and it's not about not being clean it just happens. Go see your doctor and they can do a swab and treat you and you'll be fine.
