Red Pepper has an adequate, if short, article on Christianity's War on Sex - pointing out something that a lot of sources seem to ignore. The Christian sexuality network is far from anti-sex; they're pro-sex, but twisting it in a way to make their goals towards control achieved. Institutional control over people's bodies swings many ways, they point out the Nazi manipulation of sexuality, and I'll include Italy's "conceive babies to build an army" push during fascism: sex is sex, unless you let someone control it for you...then it becomes something nasty.
