Well, that isn't quite what Chinese medicine claims. Men have female energy and women have male energy, true, but not in a 50-50 proportion to their predominant energy - there is a balance to be achieved. Most Americans today have way too much of the opposite energy, thanks to feminist-inspired media behavioral models. And the alternate energy doesn't translate directly into sexual desire for the same sex - it just leads to wuss behavior in men - like admiring Ben Affleck and voting for Democrats. ;)
I don't think there is such a thing as a bisexual man - those who claim to be are lying homosexuals who hurt women and use them as "beards" to gain social acceptance. Bisexual women, on the other hand, are very common and may even be the norm. Male and female brains are just wired differently.
Some people will use anything to justify their behavior or for publicity. Just more of the same agenda driven dribble.
