Quiet
If you take your vibrator into your bedroom and close the door, "quiet" means that people outside shouldn't hear it. A few products in this category, particularly the remote-controlled ones, will be so quiet that you can run them in a public place without anybody hearing, as long as there's some level of background noise, such as people talking or the dialogue in an action-adventure movie. Don't expect miracles though! Vibrators are powered by electric motors and do make some noise, regardless of how "whisper quiet" they claim to be.

Average
Your next-door neighbor won't hear an "average" vibrator , but somebody outside your closed bedroom door might hear a sound not unlike an electric razor. This isn't the kind of toy you'd be able to hide from your lover or housemates while you're using it, but it also won't be like a siren to announce you're having an evening of pleasure.

Loud, but Worth It!
The more powerful vibrators come with a downside -- don't expect people not to hear you using them! If you want the most power, often times you'll be sacrificing discretion. But aren't those orgasms worth it?

When considering a traditional vibrator, think about what you want. Some people (especially newcomers) prefer the simple sleekness of the frictionless silver bullet vibrator. Others enjoy a more realistic shape and texture. Some people like small traditional vibrators and others like obscenely large ones. It's really up to you. You might try experimenting with different vegetables to determine what size works best for you; however, please thoroughly wash your veggie of choice before inserting it anywhere! When you find a veggie that fits just right, hunt for a traditional vibe of approximate size and shape. If you're not comfortable with the vegetarian approach, you may have to let trial and error determine your acceptable girth. As for texture, stroke a few floor models if you're shopping live. Pick the material that appeals to you most. If you don't find it potentially erotic, it's a colossal waste of time.

Traditional vibes are available in a variety of different styles, most of which can be categorized into the following groups:

• Slimline Vibrators: Also called "smoothies," these more traditional units are usually made from plastic. A favorite with novices, slimline vibes can induce powerful orgasms from both internal and clitoral stimulation. Their frictionless exterior makes slimline vibes a poor choice for thrusting movements, but the gentle internal pressure can be quite nice.
• Realistic Vibrators: These beefy units look just like the real thing: veins, testicles and all. Internally powered by batteries, these vibes are perfect for people who love intercourse with a powerful twist.
• Personal Massagers: These discreet units resemble anything but the male member. Ergonomically designed to fit the female body, these discreet vibrators have a slightly hourglass shape.
• Vibrator Sleeves: Made to slip over slimline vibrators, sleeves are made from silicone, Cyberskin ^TM, jelly or rubber. Sleeves can resemble anything from penises to knob-studded cucumbers to cute little bunnies, and produce an enticing and versatile array of sensations.

Some women prefer traditional vibes because using them seems more like traditional intercourse, with a big, pulsating bonus. In fact, some men have been known to become jealous of their partner's vibrating buddy -- why would any woman with a vibrating penis at her disposal want a big, messy man around the house? Never fear, guys. A traditional vibe can provide crashing orgasms, but it can't provide the intimacy and touch that you can.

Three additional things are critical for safe anal play: communication, relaxation, and lots and lots of lubrication. Unlike a woman's vagina, the anal canal doesn't produce any sort of lubrication. The last thing you want to experience during anal play is the sharp, shooting pains that can accompany the insertion of a dry vibrator. Take it slow, be gentle, and respect your partner's boundaries.

Possibly the weirdest looking of all sex toys, anal vibrators closely resemble sea cucumbers: they're oblong, knobby, spiky and pliant. A titillating combination of vibrator and butt plug, anal vibrators can have variable speeds, internal or external power supplies, and fancy features -- just like other vibrators. Use an anal vibrator if you enjoy the sensation of fullness and pulsation -- a wickedly delicious duo!

Many of these designs are usually for external use only -- as these "novelty" vibrators are sometimes of specious design, it's entirely possible for the vibrating unit to become detached from the cord and lodge itself somewhere you can't quite reach. While this kind of situation is hilarious for emergency room personnel, it's probably not something you want to experience. So unless the unit is specifically designed for internal use, play it safe and only use it externally.

Most women use these toys as they would a traditional vibrator -- as a vibrating penetration tool. However, the G-Spot vibrator's curved end or knobby middle hits in just the right spot, providing the added pressure that many women enjoy.

Clitoral Vibrating Eggs
The most common type of clitoral vibe is small, egg-shaped and attached to a multi-speed battery pack by a long cord. Variations on the basic design include more narrow, bullet-shaped vibes, and vibrators shaped like cats, bunnies, bears, dewdrops, miniature rocket vibrators and large human tongues. Whichever design you choose, basic operation is the same -- focused vibrations at varying speeds and intensities. The best thing about these handy little vibes is their level of control: all the fancy bells and whistles ensure you get precisely the clitoral pulse you require for a mind-shattering orgasm.

Insertable Clitoral Vibrators
These insertable vibrators often have a small animal, such as a rabbit, bear, dolphin or beaver, perched near the base of the vibrator and facing forward. In addition to making you giggle, your animal friend will provide clitoral vibrations while you insert the shaft into your vagina. Fancy models also come equipped with a rotating band of beads or "pearls," which can provide G-Spot stimulation. Before you go out and purchase one of these fabulous (and expensive) tools, consider what you're buying. Can you handle simultaneous clitoral, vaginal and G-Spot stimulation? You betcha!

Electric Vibrators
Large, obtrusive and ostensibly intended for body massage, electric vibrators provide an incredibly powerful genital buzz. The Hitachi Magic Wand is the longtime favorite of electric vibe enthusiasts, but many other brands of wand will suffice quite nicely. Usually about a foot long, these vibes plug into a wall socket and usually have variable-speed controls. The unit consists of a long handle topped with a soft, vibrating head approximately the size and shape of a tennis ball. While you can, technically, use these vibrators for back and body massage, we highly recommend squeezing them between your thighs for an intense rush of electricity. Not for the timid.

A variation on the standard electric wand, the coil vibrator is reminiscent of the battery-operated manicure sets popular in the 1980s. About the size and shape of a handheld electric mixer, the coil vibrator is topped with an interchangeable set of heads, which can include soft, round, bumpy and textured tips. This vibe produces an incredibly intense sensation and is almost noise-free. Some women find the sensation too intense; others just can't get enough.

Numerous attachments are available for both wand and coil-style electric vibrators. Ranging from the tame to the utterly wacky, these attachments can include suction cups, G-Spot wands, dual penetrators, cups, bulbs and soft rubber rings. We recommend trying the wand or coil alone, then adding attachments as your sense of adventure dictates.

Hands-Free Clitoral Stimulators
Designed to resemble a harness or pair of G-string panties, the hands-free clitoral stimulators (also called a "butterfly" vibe) is a small, intense vibrator held fast to a woman's clitoris for an intense, localized vibration. The miniature motor is housed in a plastic casing resembling a butterfly, dragonfly or some other kind of cute forest creature.

The sensations produced by these happy little critters can be incredibly strong -- too strong for some women's tastes. If you enjoy a deep, intense vibration, the butterfly vibe might be a great option for you, especially if you fancy wearing it out of the house. Yes, it's true: some women really get a kick out of wearing their vibrating panties to work. And why not? A quick rush of blood to the groin area might be just what you need to get through the day if you have a boring job. For added excitement, try a remote-controlled panty. Your significant other will enjoy randomly turning you on and off during a movie, grocery shopping trip, bowling game, etc. Warning: these vibes do make noise, so only use it if you're relatively alone, there's plenty of background noise or if you don't care if people know your little secret.

While many butterfly vibrators have larger harnesses that make them only good for solo use, a number of newer models have been designed with less obtrusive harnesses and smaller units so that they can be worn during intercourse, adding clitoral vibrations to the excitement of penetration.
