Good that these kids don't confuse love with sex.
They know their families love them and even understand/advocate the concept of loving your enemies. And they know their pets love them.
Sex isn't needed to make love any more genuine.
i asked my 6 yr old the question and lela said love is like having warm brownies in your tummy. you cant eat too many or you get get a tummy ache. you have to have just enough to make it right. go figure.......
