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
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'."
