Other Kinds of Vibrators
Personal Massagers
In the 70s, the Hitachi Magic Wand showed us how personal a massager can get. And while the HMW is still the gold standard (nothing else has its raw power), there's a wide variety for any need and budget. Personal massagers are generally used externally, giving full focus to the clitoris. If you want the power inside you, extensions for internal use are also available.
Spot Vibrators
Sometimes, you know exactly what you want and exactly where you want it: that's when a spot vibrator delivers. The most popular spot vibrator is the "butterfly" vibe, which straps on over your clit and doesn't stop until you want it to. The great thing about a butterfly vibe is that it's entirely hands free, and won't come off until you want it to. Remote-controlled butterflies are also available, if you're playing with a partner.
The Fukuoku finger massagers are a different approach, ten small vibrators that clip to your fingers. If you can't think of at least twelve wicked things to do with these, you're not trying hard enough.
Vibrating Panties
The principle is simple: it's underwear that gets you off, Vibrating panties come in regular and crotchless, for when you don't want to wait. Some types allow you to use your personal bullet vibrator, others contain their own vibrating element. They're generally comfortable enough to wear for extended periods, so you can stay on the edge of orgasm for as long as you can stand.
Some types of vibrating panties operate by remote control, and you can get into a lot of trouble with these. Slip these on your lover and let the games begin. Theoretically, you'll be able to make her come without touching her. However, odds are that she won't be able to keep her hands of you before then.
