You should notice that even in the "straight" population, a woman's sexual orientation is not nearly as big a deal as a guy's. Most women and men will hang with a lesbian/bi or work with them, no problem. When we get to male oreintation it's a different matter. Males who are percieved as gay have a larger percentage of the population that feel "funny" about interacting with them. I don't know if it is an american thing or just a male thing. Many men are intigued by a bisexual women but put-off by a bisexual man. Go figure!
