Dildos: How to Choose One, Use One, and Never Buy a Toxic One

The oldest sex toy in human history, and the one most likely to be quietly poisoning you if you buy the wrong one.

Archaeologists keep digging up dildos. Carved siltstone, polished antler, smoothed stone, some of them tens of thousands of years old, shaped exactly the way you would shape one today. The dildo is very likely the oldest sex toy humans have ever made, older than the wheel by a wide margin. Women have always known what their bodies wanted to be filled with.

What is new is that somewhere along the way the market started making them out of materials that can quietly harm you. So before anything else, before shape and size and the fun parts, there is one thing you need to know, and almost no one selling these toys will tell you plainly.

The toy, plainly

What a Dildo Actually Is

No motor, no vibration. Built to fill, to thrust, and to leave your hands free.

A dildo is a phallic toy made for penetration. No motor, no vibration, no battery. That is the whole point of it and the whole charm. Where a vibrator buzzes, a dildo fills. It is built for the sensation of being entered, for the slow drag of thrusting, for steady fullness held in place.

What it gives you that a partner sometimes cannot is total control. You set the angle, the depth, the pace, every single time, with no one to read and no one to please. And because your hands are free in a way they never are during partnered penetration, a dildo pairs beautifully with clitoral touch, which is the combination most women's bodies actually need to come. A model with a suction base goes one step further: stick it to the floor of the shower or the side of the tub or a hardwood chair, and it holds itself while both of your hands go where you want them.

That is the machine. Filling, thrusting, pairing, hands-free. Now the part that matters most.

The one rule to memorize

The Material Rule That Matters Most

Silicone, glass, or steel. Walk away from everything else. This is a health issue, not snobbery.

Here is the rule, and it is the one thing in this entire piece I would ask you to memorize: buy silicone, glass, or stainless steel, and walk away from everything else.

This is a health issue, not snobbery. The materials that are safe to put inside your body are nonporous. Medical-grade silicone, borosilicate glass, and polished stainless steel are sealed solid at a microscopic level, with no pores for bacteria or fluids to hide in. You can clean them completely. They will not leach anything into you.

The materials to avoid are porous. Jelly rubber, PVC, TPE, and anything labeled vaguely as "novelty" are riddled with microscopic pockets, like a dense sponge. Bacteria and yeast slip into those pockets and breed there, and no amount of soap reaches them. Use these toys and you can end up with recurring infections you never connect to the cause. Worse, jelly and soft PVC are usually made soft by phthalates, the same chemical family flagged for hormone disruption, sitting against the most absorbent tissue you have.

Your body, not the photo

How to Choose One

Most first-time buyers get the priorities backward. Here they are in order.

The four selection rules, in priority order
  1. Girth over length

    The sensation of fullness comes from width, not from inches. Length past a certain point just hits your cervix, which is not the goal. Start narrower than you think you want, somewhere around an inch to an inch and a half across, and size up later if you crave more.

  2. Curve for the G-spot

    A gently curved shaft, angled up toward the front wall of your vagina, is built to reach the G-spot. Straight shapes are the easiest place to begin. A curve is the upgrade once you know what you are reaching for, used with firm, rhythmic pressure toward your navel.

  3. Start modest

    Arousal relaxes the muscles, so the size that feels right when you are warmed up is smaller than the one that looks impressive in a photo. Ambition is the enemy of a good first night.

  4. Flared base for anything anal

    Anything that goes near the anus must have a wide, flared base that physically cannot pass through. The rectum draws things in and does not let go, and a toy without a stopper becomes an emergency-room visit. This rule has no exceptions.

Strap-ons, Briefly

What it adds, and where the full guide lives.

A strap-on is a dildo, usually flared-base silicone, worn in a harness so it can be used hands-free to penetrate a partner. It opens penetration to bodies and pairings that the default script leaves out, and it puts the giving role in the wearer's hands.

For a woman, the most common strap-on act is pegging, where she wears the harness and penetrates her male partner. That has its own anatomy, its own conversation, and its own slow first-time sequence, and we have written the whole thing already. The full guide lives in our pegging feature. Start there before you buy a harness.

A real market, said plainly

The Fantasy Category, Without Shame

Bad Dragon and the fantasy makers, explained: imaginative shapes, body-safe material, nothing to apologize for.

There is an entire world of dildos shaped like nothing human, and it deserves a plain, unembarrassed explanation. Companies like Bad Dragon make fantasy toys, dragons, other creatures, imaginative forms, hand-poured in the United States from platinum-cured, body-safe silicone. The material is the safe kind. The shapes are the imaginative kind.

This is a real and large market with a frank, no-shame community around it. People customize size, firmness, and color, and they talk about their choices openly, because there is nothing to be ashamed of. A fantasy toy is a body-safe silicone dildo with an unusual shape. That is the entire story. If the form appeals to you, the only thing that matters is the same thing that always matters: that it is genuine body-safe silicone, which the reputable makers are. What turns you on is yours, and the imagination is allowed in the bedroom.

The part most guides skip

How to Use One Well

Lube matched to the material, angle and pace that are yours, and the pairing that does the real work.

Four moves that change the night
  1. Lube, matched to the material

    On a silicone toy, use a water-based lube only, because silicone lube can bond to silicone and ruin the toy's surface. On glass or stainless steel, any lube is fine. When in doubt, water-based is never wrong.

  2. Angle and pace are yours

    Go slow at the start, let arousal build, and aim a curved toy toward the front wall. There is no performance here and no one watching. Move it the way your own body asks.

  3. Pair it with your clitoris

    This is the single highest-value move. Most women need clitoral stimulation to reach orgasm, and a dildo leaves your hand, your other hand, or a small vibrator completely free to provide it. The filling and the clitoral touch together are what the research keeps pointing to.

  4. The suction-cup discovery

    Mount a suction-base toy on a smooth wall, the shower, the tub edge, or a sturdy chair, and you have hands-free penetration at whatever rhythm you set with your hips. You may rediscover this one the way so many women do, like finding a secret, because both hands stay free and the pace is entirely your own.

The filling and the clitoral touch together are what the research keeps pointing to. The toy frees you to do both at once.
Keep it safe between uses

Cleaning and Storage

The same nonporous surface that keeps you safe also makes the cleanup simple.

Wash with warm water and mild soap before the first use and after every use, then air-dry fully before putting it away. Nonporous toys can go further: medical-grade silicone, glass, and steel can be sterilized by boiling for a few minutes, and most silicone is even dishwasher-safe on the top rack. Store toys separately, not touching each other, since some materials react when left in contact. A cloth bag or a dedicated drawer keeps them clean and keeps the question off your nightstand. Porous toys cannot be fully cleaned no matter what you do, which is the final reason to never buy them.

Comfort is a feature

Choosing One in Midlife

This is exactly when a dildo earns its place.

This is exactly when a dildo earns its place. Lubrication changes in your 40s and 50s are common and ordinary, and they are not a verdict on your desire. A good water-based lube and a smooth body-safe toy work together easily and make penetration comfortable on your terms. The control matters more now too: you set the depth and the angle, so nothing has to hurt, and the pillow-and-pace logic that makes partnered sex comfortable applies just as well solo. And the hands-free, clitoris-paired use is the most reliable route to orgasm there is, available any night you want it, with no one to negotiate with.

Tonight's experiment

The Whole Assignment

One material rule, one curve, one paired hand.

If you already own a toy, check what it is made of right now, and if you cannot confirm it is medical-grade silicone, glass, or steel, retire it tonight. If you are buying your first, choose body-safe silicone, modest girth, a gentle curve, and a flared base. Then use it the way the research keeps recommending: one hand or a small vibrator on your clitoris while the toy does the filling, slow, at a pace you set and answer to no one for.

Dildos: FAQ

What is a dildo?
A dildo is a phallic toy designed for penetration, with no vibration or motor. It is made for the sensation of being filled, for thrusting, and for steady fullness, and it gives you full control of depth, angle, and pace. Because it leaves your hands free, it pairs easily with clitoral touch, which is the combination most women's bodies need to reach orgasm.
What dildo material is safe?
Medical-grade silicone, borosilicate glass, and polished stainless steel are body-safe. They are nonporous, which means they can be cleaned completely and will not harbor bacteria or leach chemicals. Avoid jelly, PVC, TPE, and anything labeled vaguely as "novelty," which are porous and often contain phthalates. If a toy does not clearly say medical-grade or platinum silicone, treat it as unsafe.
How do you choose a dildo?
Settle the material first, then prioritize girth over length, since fullness comes from width. Start modest in size, choose a gently curved shape if you want G-spot stimulation, and insist on a flared base for anything that goes near the anus, because the rectum can draw a toy in and a flared base is the only thing that prevents it.
How do you use a dildo?
Use a water-based lube on silicone toys and any lube on glass or steel, go slowly as arousal builds, and aim a curved toy toward the front wall of the vagina. The highest-value move is pairing it with clitoral stimulation from your free hand or a small vibrator. A suction-base toy mounted on a wall or chair gives you hands-free penetration at your own pace.
