Purely a matter of curiosity here... The girl I'm dating and I had sex for the first time last night. I had to take it really, really slow and could really only put the tip in because it was hurting her too much. I know she's not a virgin, and I would have thought that previous guys she's been with would have stretched her out some. I'm slightly above average size-wise but am by no means huge. So what happened? Does the vagina get tighter in young women if they haven't had sex in a while?
