This immediately made me think of the Sting song "Straight to my Heart", and the 'sex' scene in "Demolition Man". I'm sure there are other examples.
I suspect that if sex/ sexuality were not in such an odd cultural space, ideas like this would either rarely arise, or at least never raise an eyebrow.
For anyone in the Vancouver area, Joe is a Guest of Honor at VCON (http://vcon.ca), in the first weekend of October. It's a smallish convention, so GoH are usually easy to find and chat with.
Full disclosure, I am helping put on the convention, but it's a non-profit convention put on by volunteers.
