This is an old post but I am a guy who does not want sex with his girlfriend. I am not cheating just don't get to the point were I want to. I think its a mix of things, like work and the stress of life, but also I think we are not in sink with each other. When I do have disire she does not and likewise when she wants I don't. We have been together 5 years and it is hard to talk about but we did and we will not push it for now and just go to that level unless we both are in the mood.
