My girlfriend has admitted to being a sex addict. In normal circumstances this is the perfect match for me as I am rather sex obsessed myself. The catch here is the fact that we are in an a long distance relationship (500 Mile away). We see each other one long weekend every 10 days. She has a history of using men like toys and I find that part kind of hot. She is very erotic and likes showing off her guy to her girl friends... such as when she like to get me hard in public. Anyway, she recently gave me a surprise. She tells me that because of the long distance she can no longer wait 10 days or so for a weekend of non-stop sex. So I either move to her city or she wants an open relationship. She has a big corporate job and makes more money than I do. I have not cheated on her. She has admitted to cheating on me once with a women. I have obvious concerns about an open relationship. I really am into her but the idea of her having sex with other men without me, turns me off. Most women that I have dated develop such strong emotional connections that it is very difficult for them to cheat. This girl however thinks more like a guy. She told me that she first decided to date me because "you have a big cock and your body is light".... the combo gives her the strongest orgasms. She likes a big cock inside her with a dude laying on top. If the cock is small she does not cum, if the guy is too heavy she feels crushed and cannot cum. I'd like to think my relationship is stronger than good sex. However, I am very mindful of the fact that it was good sex that got her interested in the first place. She is a size queen. She also is into black men. I am the first white guy she has dated in a number of years (she is white). This fact makes me a little self conscious that she is craving sex with a black man. Her request for an open relationship is like a "I want to have cake and eat it too situation." I predict that if we go into an open relationship we will both have lots of sex on the side and it will cause jealousy conflicts. Does anyone have a successful open relationship?
