Missy Elliott is on to something: Toys can be titillating. "Vibrators provide one of the strongest and most consistent forms of stimulation," says Judy Kuriansky, PhD, sex therapist and author of Generation Sex. Introduce the buzz factor once you've prepped yourself for pleasure, and it could make an orgasm a sure thing. But you have to know how to summon the sensations. Begin by working the vibrator over your clitoris, using the same techniques as described previously. (You may want to keep your panties on at first as a buffer; the buzz can be intense.) Then tease yourself by alternating speeds as your desire builds. Just remember to switch up your routine. "Vibrators are great training wheels, especially for the gal who thinks she'll never get there," says Kuriansky. A word of caution though: Too much humming can potentially cause your nerve endings to become somewhat desensitized. Pace your usage of this joy stick and let your fingers do the work on the off days. Now that you know what makes your body tick, it's time to share your stimulating secrets with someone you love...or at least lust for.
