Is it a common fantasy among bi women to imagine their male partner having sex with another female? I had a bi girlfriend who said this was a major turn-on for her. She said what she really liked about it was that she'd know exactly what the other girl was feeling when she was fucking me (which I don't agree with since each woman is a lil different). Was she an odd one or do other women think about it? And I guess you really have to be bi or bi-curious to think about such a thing the first place so that's why I addressed the question to bi-s only. I don't mean to exclude people.
