I've been dating the same girl for almost two years. The relationship is great on almost every level. The problem is that she physically isn't what I usually go for. She is a short petite blond, but my preference is tall thick brunettes. We have our best sex when I have a couple drinks and fantasize about ex- hoookups. Does anybody know of a way to help me increase my sexual desire for her? She means a lot to me and I don't want to end things because of something so shallow. I've cheated in quite a few of my last relationships and I don't really want to go down that road.
