I've been dating a woman for around two years. For about the first 6 months of our relationship, we had frequent sex and my drive was quenched. I would describe myself as a very sexual man and my primary need in a relationship is sexual fulfillment. Recently, it seems as if I have to twist her arm to get her to have sex and getting to the act seems like a hurdle. My lack of gratification in the relationship has let to several break ups. Everything about the relationship is awesome, except for the sex. I've tried to hang on to everything else...but since my needs haven't been met for the past 18 months, the road has been rocky. It doesn't seem like she cares about what I need from the relationship. I want a lover, not a friend.
