The most common "cure" i have heard for "sleeping around" is to freeze marbles-- and pour them onto the appropiate anatomy- and point out to the partner -- "it could have just as easily been boilling water.. "

cold marbles work well, too, to get children out of the bed.. cheap, reusable, and they don't melt into puddles..

and at family picnics, as things settle down, but the children still have way to much energy- have them warm some water to temid (over the dieing coals)-- and then find cousin/uncle/friend who has "fallen asleep" and dip their hand in the warm water..---a most embarrassing moment!
