I've never understood the passion for watching two girls go at it.............I mean, I love women and sex but watching two girls has simply never done anything for me. However, if it was a threesome she was after, I'd go for it.
All of our encounters have turned into a threesome. A lot of times, the girls just want to fool around at first. Then everyone gets turned on and it goes from there. Most bi women I know, obviously, love pussy, but dick, too. And if a man is in the bed, it goes from there. I've always let my girlfriend take the lead when it comes to approaching women. Other women are less threatening to each other.
A common icebreaker I've heard both ways is " I love your dress", or your shoes, or your hair...
Women can say that to each other without seeming "weird". Most men don't do that to each other, obviously. But women can compliment each other and often times it goes from there.
Like I've posted before, I'm 31, never married, and never wanted it. I've had lots of women...not to toot my own horn, just a fact. It's taken me lots and lots to find her...but damn, well worth it.
