Actually, I think you might be contradicting yourself here.
When you mention divorce rates skyrocketing, I don't think you're accounting for all the people getting a divorce BECAUSE they waited until marriage for sex. In other words, you have to take into consideration the amount of people supporting your point of view that do wait until marriage for sex, even couples who immaturely vow to bond as one for the rest of their lives thinking only about the act, only to find themselves disappointed once they realize their significant other isn't what they expected to be in the first place.
Another great flaw I see to this point of view you are supporting is that people can't, under any circumstance, know for sure if the person they wedded is to remain their partner for life (for X or Y reason), therefore, the person whom you waited for sex until marriage turned out to be the wrong one, subsequently, contradicting itself once again.
Sex is a completely natural part of life, and not meant to be shared by a "special someone", at least not by definition.
