Any one else have issues with hitting the cervix or whatever with girls. I'm around 8in, and like smaller framed girls. Problem is I need to be very physical to orgasm, and it doesn't help that I am the kind of guy who can go for almost an hour without one. The girls love it, but sometimes I get so into it, I go really fast and end up hurting them which of course ruins the mood for both of us. Also, any tips on getting off faster?
