You could give it a whirl I guess. The folks that I know who have many (5+) kids are religious jews, catholics, muslims and mormons. I don't know if all of these people have defered sex till marriage but they are certainly not the ones racking up tripple or even double digit bodycounts. Are you saying you have a line of reasoning that people who maintain religious adherence today are doing it so they can have unrestrained sex?
