I'm not quite sure what you mean, Hundredmillion. But I'm hoping you're indicating that you partially understand my annoyance here.
The central reductionist fallacy I hear severely heteronormatively straight males cite over and over is that sexuality is all biological and somehow "above" or "below" the influence of psycho-social factors in its formation. They will insist that something like, say, breast implants work because men just can't help loving big breasts because biologically men are "wired" to be hopelessly attracted to the biggest, most unnaturally large-looking breasts imaginable. This is always with no reference to the fetishitic nature of sexuality in general, let alone the obvious fetishism inherent in so many of our cartoonishly ridiculous post-secondary exaggerations of secondary sex characteristics in our sexual imagery. There's never any acknowledgement that biologically, disproportionately large breasts would actually indicate an elevated risk of heart disease at very least, and a lot of things that aren't necessarily genetically desirable at worst. I can't stand reductionism w/r/t sexuality, coming from anyone.
The same straight men who adhere most strictly to this usually cling hardest to the idea that women somehow aren't as biologically sexual as men. You know the drill. Virgins/whores. There's the mom figure (and her replacement, the "wifey" girlfriend), then the sex toys that appear in magazines and DVDs at their whim for their complete silent unchallenged unreciprocal gratification. The ones who think it's absolutely disgusting to see men in a speedo (in America, at least) or absolutely biologically wrong for men to preen, while it's perfectly natural and obviously aesthetically favorable for women to be seen as a bunch of parts. It's perfectly natural for female worth to be measured in units based on how desperately men want to see her in a bikini. They're also the jealous types who think they own you if they've touched you, and get upset at the thought that you've had previous lovers. It's all exhaustingly boring-to-repulsive for women, who end up only seeking male attention out of neurotic desperation to feel "worthy" of it.
Like that Courtney Love song, "I am/doll parts." hehe. My friend with PTSD loves Courtney Love, which makes a lot of sense, doesn't it?
