I am having sex with a girl who was virgin almost like 20 days ago.. I had sex with her 4 times.. the first two times hurt ( she was virgin) i think the second time hurt because she was sore i think from the first day was about two days after... then the third time we did it she end up with shaking her legs and abdomen like if it was cold.. like shivering but a lot... then the last time we had sex she came 4 times i cam e 2 .. and she say ech tiem it feels better! but the fourth time it is like if she was tight to get in and she say it hurt at first! .... will this go on? or this is normal that she is tight and i am fat? hmmm anyone with similar experiences?
