I'm a housewife and in an open marriage. It's always been that way for us, since we started dating 6 years ago. We're extremely compatible with each other, beyond some sexual incompatibility. That's kind of why I'm on here.
My husband is one of the coolest people in the world, and if you were interested in being my friend with benefits to fill in the gaps where we're not compatible, you'd meet him. That's not negotiable. We don't hide things from each other or have secrets. He's fun to hang out with.
I'm also looking to put the "friend" in "friend with benefits" -- I like just hanging out, doing something other than being naked. I've tried the exclusively naked thing, and it just doesn't work for me. For sex to be good for me, I need a connection on a personal level, to be able to just watch Netflix and hang out or whatever.
