I confided in one of my close friends (a girl) that I've been considering a 3some (me and 2 guys). She was excited and told me that she'd really like to see me doing it with 2 guys and I should add some girls to the equation (some girls being her and some of my other close girl friends). I was quite shocked because this close friend of mine is actually a lot like a sister to me. Worst, she wasn't kidding. Is she bi or just curious?
