I'd mark "bi-curious" but explain in your profile. Especially if you don't just want one-on-one play with a man.
Young isn't into men, but isn't going to run screaming from the room if a penis gets near him. We had an experience recently with a pile of people where Young looked down and saw a man sucking him. He just said something like, "No thanks. I'm not into guys" and the guy moved along. The whole thing was spontaneous and nobody had to ask explicitly to touch, but if a touch was unwanted, we just said so.
So clear wording is important in your profile, but having a little mystery makes conversation interesting. If a couple isn't interested in a bi male maybe just skip that part. I like women sometimes, but the attraction must be there, as with anyone. Asking will rarely get you booted as long as you respect the "No", but that doesn't sound like it's a big problem for you.
