Want to see Christianity fuck up sexuality firsthand?
During my most recent bout of insomnia, I busted out the Netflix and found the series, "Sexual Healing." I'm a little surprised that I'd never seen it before, but it's not a bad show at all. Each episode follows two or three couples for a week of daily relationship and sex therapy. Unlike so much reality claptrap, this is emotionally mature stuff about real people having very real problems.
If you don't have netflix, or something similar, here's a link to the episode that made me quit watching -- not because it was a bad show, but because I was so mad for the couples whose relationships and sex lives had been completely fucked by Christian beliefs. (It's episode 4, by the way.)
Briefly, there are two Christian couples. One had a great dating life, and the woman was adventurous, sensual, and had great fun in bed. Then, they decided not to have sex until marriage -- a year and a half hiatus. The poor girl says at one point that she just had to "turn off" her desire for sex and all the pleasure she got from it. Well, it worked. They're married, and she doesn't want to have sex. The guy is, to be blunt, one of the worst kinds of Christian sons of bitches. He's a control freak who thinks that if he just smiles constantly and tells you about Jesus, everything will be perfect in his little world.
Second is a couple where the guy was the girls' first. They've stayed together for years because she felt so guilty about losing her virginity that she never considered leaving him for someone she actually liked.
If there's any way you can spend the fifty minutes or so watching this episode, I highly recommend it. It's one thing to talk about the damage that Christianity does to people, but it's entirely another when you get to see them break down with a therapist and completely lose their shit.
[EDIT: Forgot to mention, that link will charge you $1.99 for the episode. I don't know if it's available for free anywhere else, but I certainly don't want to piss off Showtime by posting it here if it is.]
