my gf and I have a very healthy relationship, and one that has been very sexually active, I was her first ect ect, but we have discovered a problem, and that is no matter how wet she gets or how horny she is sex simply hurts her, and were not sure why? It seems that only a few times has it actually felt good for her, and we are kinda wondering why? and maybe for some tips on how to allow her to enjoy sex more.
