Why booty's always on his brain

Ever notice how one minute your guy's watching the match, then the next he's pawing you?

His tootsies have a secret turn-on zone

Keep this in mind next time you give your man a foot massage: "The insides of a man's ankles are sensitive because they are neurologically connected to his sex organs, so rubbing them will intensify his pleasure," says Larry Costa, author of Massage: Mind And Body.

To make your man rock hard, try feeding him pumpkin seeds and peanuts. They contain L-arginine, an amino acid that can increase blood flow to the penis, says Mehmet Oz, M.D., professor of surgery at Columbia University College of Physicians and Surgeons, US.

Oral action has a surprising side effect

Warming lube can amp up arousal

New warming liquids really kick nooky up a notch. "They heat skin upon contact, which can enhance intimacy and heighten sexual arousal," says Yvonne K. Fulbright, an instructor of human sexuality at the University of New York and author of The Hot Guide To Safer Sex. To give him a tingly sensation, rub a few drops of warming liquid onto his testicles and then work back to his perineum (the area between his testicles and tush).
