Is it normal for vagina to close up during sex?
Okay here's the situation.
There's this girl, that, everytime she gets turned on and during foreplay she gets naturally lubricated and everything like normal. When we start to have sex everything is normal. Once I stop for whatever reason and pull out, even for 20 seconds, once I go to get back in she is unbelieveably tight. Like I can't get back in, it is just like her vagina is completely closed up. I have to start working her up again with my fingers and with foreplay until she is loose enough for me to get it back in. I am not complaining because it feels fine once we start again, but I have never experienced this odd 'vagina closing' with any other girl.
I do not have an unusually large penis or anything, it is average I would say. I am 26, she is 23. She hasnt had any kids.
I have never slept with a girl whose vagina does this and I have been with a few different girls. Is this normal? What does it mean (if anything)?
