I am trying to find as much information as I can about this because I love her and want to make it better, but I don't want to hurt her feelings.  When we started our relationship and mostly after a few months we engaged in oral sex and she was always very aroused and this is still the case.  She no longer gives as much as she receives and when she does it is for 2 minutes then she says her jaw hurts and she cannot continue.  We have also stopped having sex since she claims since we don’t see each other so often it hurts when we have sex, though it has always hurt her and we tried KY to no avail.  Lately she doesn’t even seem to want to have sex or do anything sexual and it worries me because I do frequently, and find myself feeling left out and unfulfilled when I leave to go back home after a weekend of seeing her (I am in a different school than her).  Any suggestions??

First, when performing oral sex she says her jaws hurt. But if she uses different techniques, both licking and sucking, and doesn’t attempt to put too much of the shaft in her mouth, that should make it less tiring. She should also use her hands on the shaft of your penis, so that her mouth doesn’t have to do all the work. Of course, if you know that you only have a limited time, that’s going to make it more difficult for you to have an orgasm, which in turn will mean you’ll need a longer period of oral sex to have your orgasm, and so it can become a vicious circle.

As to any pain during intercourse, is she sufficiently excited before you begin intercourse? If so, her natural lubrication should help. Of course some women will subconsciously tighten their vaginal muscles, making intercourse painful. That might come from being nervous about having sex, which could be a personal problem or a relationship issue. If that’s what is happening and it is psychological in nature, she would then benefit from some counseling, which she could probably get at her school.
