Because lying to your kids about sex helps nobody. Telling them that sex is โ€œonly between mommies and daddiesโ€ is a lie that leads to confused, hormone charged teenagers. Telling them that sex is โ€œonly something that happens when two people love each other very muchโ€ is a lie that causes hormone charged teenagers to confuse โ€œloveโ€ with โ€œlust,โ€ or โ€œobsession.โ€ It leads to leaps of logic like, โ€œIf I have sex with them, we must be in love.โ€ Or worse- โ€œIf I love them, I have to have sex with them.โ€ And how many teenage tragedies are based on that misconception?
