blossom I agree with before about ensuring lack of emotional connection is vital for a fuck buddy relationship to work. I have had 2 successful fbs. To be honest, with both of them, I didn't really like them as people, I certainly would not have wanted relationships with either, the one that went on for longest was really not a great guy at all, big player, lead girls on for sex etc. Very charming, good looking etc though, lots of fun to be around. I knew what he was and used him for it, because the sex was pretty decent. Sleepovers were only for when the visiting party was too tired/drunk to get home afterwards and it was perfectly acceptable to wake up later and toddle home without saying goodbye if the hosting party was still asleep. It really was a fuck-buddy thing, just about sex and worked really well. Personally I don't think friends-with-benefits tend to work out- with friends there are feelings involved, and the party that is more emotionally invested inevitably gets hurt.
