American Pie actress Alyson Hannigan believes sex is only good when she's left in enduring pain.

The redhead actress, engaged to her former Buffy co-star Alexis Denisof, admits aches and pains after sex are a good sign of healthy nocturnal activity.

She says, "The right amount of sex is when your muscles never recover, so that you always have a persistent aching muscle of some sort.

"When they hurt next day you're like, 'Why is that muscle hurting? Oh yeah, that's why'."
