You'd think this might be the case, but it didn't work that way for us. There's some couples who are great in bed together but just can't live with one another. My soon to be wife felt sorry for her ex, long after she and I started living together. One night she'd been at her old house with him (he bought her out of the house) signing real estate papers. We'd already played with the idea of her having sex with him again as in her words "He knows how to fuck me." Without making this a huge long story: she came home in tears and I knew what had happened. She felt bad because she hadn't told me it was going to happen and didn't want to lose me. "He was so horny, and hasn't had sex since I left and I felt so sorry for him and was letting him touch me and it all went from there. I wanted it," she said. I just led her to the bedroom, undressed her and was in her in seconds. We had explosive sex (I was having seconds) and from that point on it was much easier for us to talk about it and for months I enjoyed hot seconds and cleanup fun with my soon to be wife. When her ex found a girlfriend we all moved on and she and I married.
