Yeah, I've had a fuck buddy/friend with benefits before. A few of them, in fact (not at the same time, just at random intervals
). With all of them, we'd hang out, go out, meet up after going out separately, or just get together and fuck. Things worked well. We weren't looking for relationships, just friendships, and we worked well together physically.
Things did eventually end with all of them. With a couple of them, life just got busy, and our friendship faded away. With one of them, I was dating six other guys at the same time (only sleeping with the fuck buddy), and realized that I wanted an exclusive relationship with one of the guys, so ended things with the other guys.
The key is to keep emotions (aside from ones that go along with friendship) out of it. Don't let your heart get involved in a romantic way. As with all types of relationships, communication is the key. You both have to just want to be friends with benefits, or expectations may be raised, and things can go badly from there. Good luck!
