So I've been with my girlfriend for about 3 months now and everytime we have sex it feels good at first(for like a few minutes) then she says it stings or it hurts and I have to pull out. And we don't do it much at all, like once a week. and I dont finger her before...and she goes pee before and after too. Help me figure out whats going on. Because I also get weird if she tells me to pull out and I was just about to get it(get mad and just fall asleep)
