My girlfriend and I are polar opposites when it comes to sex. I am much more sexually experienced than her, despite the fact that I'm five years younger. When we have sex, I know how to make her cum and she loves it. She says she LOVES sex.However, I have to initiate almost everything. I always cum but it's never really earth-shaking. We only fuck in the same boring 3 positions b/c thats what she likes. She won't swallow b/c she finds cum disgusting. (She is a med student and says that the fact that its prostate/urine/etc.. it grosses her out) !!! No anal. No sex in public. The list goes on.. Am I being too demanding sexually? We've talked about these different sexual wavelengths. She swears she still has libido but she's often too tired or not feeling well. She contracted herpes several years ago from a stupid fling. This was a big obstacle at first, but we've learned to accept it and live with it. That being said, we obviously don't have sex when it's outbreak season. So, she's not holding back b/c she feels uncomfortable about that. I am starting to really miss some of my "sexual past-times" with previous partners and I really feel guilty about this. We all know that we can't change others; How can I bring back some of these pasttime practices while staying inside this relationship? I'm not looking to turn her into some sexual servant, I would just like some expansion..
