Bisexual women are seen as less of a threat to a heteronormative society - it's ok, they still fancy men, and hey now there's the possibility of a threesome! Bisexual men are deemed in the closet, in deep denial or at the very least falsely seen as putting their female partners at an increased risk of STDs. The double standard arises partly from a refusal to take women's sexuality seriously - provided the chance of straight sex is still in the equation, the girls can do whatever they want. And it's not just the straight community that refuses to take bisexuality seriously - instances of lesbians refusing to date bi women still run rampant, with the fear that they're doing it to seem trendy or that they'll eventually go back to men. For men and women, the risks of societal rejection when coming out as bi are equally high, but in different ways.
