Smooth, glowing skin Can sex really take years off your face? Absolutely, says Brame. Getting busy increases circulation to help flush out toxins and bring oxygen to the skin for that heavenly glow. Plus, when you climax your body releases estrogen, which helps boost collagen production to help ward off wrinkles. “That’s why it’s so important to maintain a healthy sex life during and after menopause, when you’re losing estrogen,” she says. In a 10-year study at Royal Edinburgh Hospital in Scotland, 3,500 participants who looked exceptionally young for their age (an average of seven to 12 years younger than they actually were) were interviewed about their lifestyle. The researchers concluded that an active sex life was the second most significant factor in how young a person looked, right after regular exercise.

QUIZ: How do you feel about your face?

Fuller lips. When you’re in love, it turns out you have something in common with Angelina Jolie (sadly, it’s not Brad Pitt).
