To my way of thinking, sterilization, birth control, etc. do not change the natural order of opposite-sex relations -- they frustrate it.

A man who gets himself "snipped" has only a one in five thousand chance of impregnating a woman. I'd call that a bit more than just frustrating any "natural order". Again, my point is that gratification has always been an end to sexual relations and that there's nothing wrong with that. After all, millions of women still crave sex after menopause and we can't be discussing procreation as the primary directive at that point can we?
