Shake Up Your Sex Positions

Call in sick, clear your schedule, and make sure you're hydrated. You're not going to want to leave your bedroom for a while. These inventive tweaks will shake up your favorite sex positions—and the results are volcanic. And just in case you need a reason to break away from your typical repertoire, know this: The more moves women try out during sex, the higher their likelihood of reaching the big O, according to the National Survey of Sexual Health and Behavior.
Plus, adding some variety can also prevent things from going stale outside the bedroom. Couples who constantly try new things together—which can include mattress play—report better romantic chemistry and higher relationship satisfaction than couples who stick to the same routine, according to research from Stony Brook University. Not to mention, trying new moves in bed causes your brain to release dopamine, the feel-good chemical that keeps you feeling hot for your partner, 

The Standard: Missionary

1. Clitty CAT
Technically called the coital alignment technique (CAT) this move maximizes clitoral contact. In fact, women who were unable to O in regular missionary were 56 percent more likely to climax using CAT, finds the Journal of Sex and Marital Therapy. Have your guy scoot two inches up from standard missionary, and wrap your legs around his thighs Rock in a forward-and-back motion as you press your pelvis up against his while he presses down against yours.
2. Knee Hugger
Lie on your back and draw your knees into your chest. Your partner should kneel, facing you, and hold your knees together for maximum tightness. Plus, this position forces him to thrust at a slower speed, so he'll last way longer.
3. The Leg Press
It's standard missionary--with a lift. Raise your legs so that your feet hug his neck or press into his chest, says Dana B. Myers, founder of BootyParlor.com and author of The Official Booty Parlor Mojo Makeover. Your guy will get even deeper penetration, and the added leverage will put you at the ideal angle for him to hit your G-spot.

The Standard: Girl On Top

1. Reverse Cowgirl
Spin yourself around so you are in the same position as girl on top, except facing his feet, says Ian Kerner, Ph.D., author of Sex Recharge. This variation allows for some serious G-spot stimulation and gives you the freedom to let your fingers wander to your hot spot...or his.
2. The Catcher
Instead of kneeling on top of him, straddle him in a squat position with your feet flat on the bed or floor, says Love. He'll enjoy the view, and you'll be in better control to hit your G-spot.
3. Easy Glider
Lie on top of your partner so your bodies are pressed together and your legs are fully extended, says Sonia Borg Ph.D., author of Marathon Sex. Then glide back and forth slowly. For slippery fun, rub massage oil over his chest and yours during foreplay.
