* What's wet, wild, comes in a bottle, and can mean the difference between great sex and an out-of-this-world orgasmic experience? No, it's not Dom Perignon. It's lube, aka personal lubricant. And if you've never tried the slippery stuff, you're missing out on some seriously slick fun. "You might think lubricant is only something for women who experience vaginal dryness, but that's absolutely not the case," says Lou Paget, author of The Big O. "We now know it can be a fabulous extra for anyone who wants to boost already amazing sex." Follow our advice for picking the right lube and using it to turn your next night of nooky into a trip to nirvana.

"Moisture can make sex much more pleasurable," says Paget. Translation: You'll have a happier ride if he can glide. "The wetter you are, the more comfortable you'll be," she says. In turn, your guy will be able to thrust more vigorously without hurting you, making both of you less inhibited. Plus, the moment you apply some goop, your below-the-belt sensitivity will skyrocket. That's what Pauline *, 32, has discovered: "Before sex, my boyfriend spreads lube on me," she says. "First it's cool, but when he rubs it in, it turn warm. That hot-cold switch drives me insane."

Lubricant also enhances your chances of climaxing. "It acts like a bridge that transfers--and increases--the pleasurable sensations you feel on your skin deep down to your nerve endings," says Hilda Hutcherson, M.D., author of What Your Mother Never Told You About Sex.

But be careful--you can overdo it. "For the most sensual feeling, your vagina should be slick but not so wet that you lose sensation," says Carol Queen, Ph.D., sex educator and staff sexologist at the California sex stores Good Vibrations. A nickel-size dollop of lube on your private parts will aid penetration without losing tightness and that sexy skin-on-skin feeling.
