Just that, really.
I’ve slept with a friend of mine a few times. It’s great - we chat and kiss and laugh and have sex but neither of us want anything else. I know him and I know absolutely that he will not want to be tied down to anything and neither will I. I’m obviously attracted to him and him to me, but that’s as far as it goes.
I can’t foresee this running into problems because of us as individuals but is this incredibly naive?
