Great sex

Every woman lubricates differently—there's no "normal" amount of wetness—and most women should be able to tell when they're good to go. About a third of young women say they experience vaginal dryness, according to researchers at Indiana University's Center for Sexual Health Promotion. "I've noticed this big trend of younger women who are dry down there," says clinical sexologist Patti Britton, Ph.D. Many of her patients rush through foreplay and aren't fully aroused before they dive right into the main event. Bad move: Getting busy without enough slippage can leave you with soreness or possibly a yeast infection. If your bedmate speeds straight to the big bang, ask him for more teasing. Better yet, playfully institute a "me first" policy, says Britton: "Once your partner gives you your first orgasm with his hand, mouth, or a toy, you'll likely have enough lubrication to make round two more comfortable."
