OMG. Just showed the article to some people here at work (all non Mormons) and one response was, "Oh yeah. The Provo Dip! Haha." Said they are famous for it haha again.
Once again proving all the old sayings true and this time it's, "Where there's a will, there's a way."
The weirdest part to me was having someone else there to jump on the bed. I guess if you are used to having some watch you all the time, that's not a problem?
Say a 'good' mormon boy has a nonmember girlfriend, who has nothing against sex, so he tells her she can 'move' all she wants after he's penetrated her, but because "soaking" is a way for him to avoid sexual censure, he will remain perfectly still . . .
