Easier bisexual initiations-- Boys or girls?

If you're bi, and you ewnjoy group sex, you've probably had it with some hetero and some bis. And if you're like me you get a special buzz introducing a partner to the taste of theirn own gender for the first time. There's always a little resisitance from heteros, for fear it'll convert them permenently, but a lot of them get over that fast.. I've had this discussion with both men and women, but i'll put it out to you guys: Who is easier to convert, boys or girls?
