Mormons Can't Do That!
My knee-jerk reaction was to think "Hell no! Mormons can't do that." But after thinking about it for a minute, I suppose it depends. If you're married and the person you're having phone sex with is your spouse, then I guess you could have phone sex, but with Bush and Dick listening to all your calls, would you really want to?
But if you're unmarried or the person with whom you're having phone sex is not your spouse, then dear readers, the answer would be no, Mormons can't do that.
