re: #166 chadu
I blame Greco-Roman statuary.
(I seriously have a theory about this, and its effect on “ambiguously bi-the-way” female and stereotypical gay male porn/concepts of beauty/sexiness, and why Rubenesque women and bearish males straight or gay are not typical.)
It has a lot to do with the fact that human sexuality is too complex to be shoehorned into black-and-white categories or defined by stereotypes.
But that takes away all the fun from narrow-minded idiots and bigots who want to prove that their views are the only ones that count.
