You've probably heard about guys who treat Viagra like carnal candy—they don't need the get-stiff-quick drug, they just POP it to give sex extra oomph. And though there's no equivalent prescription drug for females, there are a ton of over-the-counter creams and gels that aim to give women their own booty boost. "Many women are trying out new products that increase sensation," says Jennifer Berman, M.D., director of the Female Sexual Medicine Center at UCLA. Here's everything you need to know about the sexual-enhancer craze.

What’sOut There?

Cooling products (like Vigel Passion Gel and O'My Clitoral Stimulating Gel) usually contain menthol, which causes a cold burn tingle. There are also products that aim to increase blood flow down there: Zestra® uses plant-based oils; while other products include an amino acid called L-arginine. Most of these Products are available online from their company Web sites.

Do They Really Work?

Because most of these products aren't regulated by the FDA, they don't have to be tested with clinical trials. But according to Dr. Berman, the heating and cooling products and Zestra®, which voluntarily conducted its own clinical trial, are all likely to produce the sensations they claim. The effectiveness of L-arginine, however, is unclear. Although there is scientific evidence that the amino acid dilates blood vessels when taken orally, Dr. Berman explains that using it topically may work, but it's experimental as of now.

Are They Safe?

If you have herpes, avoid products containing L-arginine, which can trigger outbreaks. If you're on any medication, you should check with your doctor to make sure it won't interact badly. (In most cases, birth-control pills are fine.)
