Moulin Rouge! star John Leguizamo is hoping his children turn into ace sports stars - so they'll be too tired for romance in their teens.
The actor is particularly dreading the time his eight-year-old daughter starts dating and plans to tire her out with soccer and hockey.
He says, "I am gonna be very protective when she grows up. I already got plans for both my kids, my son too.
"I'm just gonna keep them busy. They'll have those hormones racing but they'll be so tired they won't have any time.
"They'll be into hockey, lacrosse, I'll have them doing martial arts, whatever. Just find me a sport; I'm going to put them in everything so they're exhausted and won't have time to even think about sex."
