I don't understand why people get so upset about the visceral reaction humans are programmed to have to other humans' bodies. It's like, our sole purpose as living organisms is to procreate, and towards that end, nature has given us "physical desires" - and we've even used our intelligence to enable us to extract the pleasure from sex without getting tangled up in the complicated process and extended responsibilities of procreation.
But still, people in "polite" society insist on believing that if you acknowledge or indulge in these physical desires, then you're sub-human. I doubt that the Christian church is solely responsible, but their emphasis on the divinity of celibacy doesn't help. So we all go through life more and less (mostly less) successfully pretending that we're not moved by one of the greatest pleasures of our mortal existence - the pleasure of the flesh - when we all know in our hearts that we're just miserable hypocrites.
I feel like I just want to scream at people, "get real!" Life is short, and I don't have time to deal with society's institution of face-saving lies.
