I'm late on this post, but I'm with everyone else. If you both are serving a purpose for each other (getting great orgasms) then it looks like a win win situation to me.
Before my boyfriend I had sex buddies here and there. We would be great friends, could sit and talk, watch movies together and chill and have mind blowing sex. But we knew we were not ideal for a "real" relationship because of bad mixing personalities or different goals or whatever. It worked great. As long as you can keep from getting attached. I have a friend who always tries to turn sex buddies into boyfriends and it always ends nastily.
I still talk to a couple of my sex buddies (talking only) just because we became such great friends. My boyfriend does not mind. We don't spend 'alone' time together at all, cuz that would be too tempting. But I think it's a great idea and sometimes it's nice to have a warm body next to you and no strings.
