The idea of everyone being bisexual is nothing new - Kinsey said the same thing in 1948. But there are social inhibitions against male bisexuality.

How people list their orientation on a swinger site may not tell the whole story. Plenty of guys who label themselves as straight on the swing sites are nonetheless open to varying degrees of same-sex play. There are a lot of women who are listed as bi but who are really more "bi-passive" than anything else. (Recieving is one thing, but giving is something else.)

People do take their cues from the people around them. It seems fashionable for women to be bisexual, but the opposite is true for men. You always hear about women who want to please their guy by putting on a bi show. The idea of "bi-for-show" is nothing new. Plenty of women find the whole concept offensive, but it clearly goes on all the time.

On the other hand, any guy who is listed even as "bi-curious" might easily be catagorized as really only seeking same-sex play. A guy who is only slightly or mildly bi, but much more into women, might not want to label himself that way. If he never plays with men that might be just fine, he might be happy to stick with straight sex.
