closest i've been is a few threesomes, MMF every time though unfortunately (no gay or bi stuff), i'm workin on gettin a few FFMs and larger groups in to keep the balance...anyway, the first couple were a little awkward but after that they were fine and it was alot easier to get into it...definitely awesome, so long as everyones clear with boundaries and ground rules nothin uncomfortable or weird will happen unless thats the point lol...
