How to Choose the Right Dildo: Types, Sizes, Materials & Expert Tips

Most people start shopping with their eyes. They see something that looks hot, click on it, read the specs, get confused by five different material names and twelve size options, and close the tab feeling more lost than when they opened it. Sound familiar? Here's the trick: flip the order. Before you even glance at a product photo, ask yourself two questions. First, what do I want this thing to do? Are you after deep internal fullness? Pinpointed G-spot pressure? Something you can ride hands-free in the shower? A toy to share with your partner? The answer narrows your options by half, instantly. Second, how experienced am I with penetration? Be honest. There's zero shame in being new to this, and your answer here will steer you toward a size and feature set that'll feel good instead of intimidating. Once those two things are clear in your head, the rest of this guide turns into a simple series of yes-or-no filters. Color, brand, bells and whistles... all of that comes last. Function first, pretty second.

This is your biggest filter. Every dildo type is built around a specific job, sensation, or a specific situation. Some overlap (a realistic dildo with a suction cup base, a curved toy that also vibrates), and that's totally fine. But knowing which primary function you care about most will cut your options down to a manageable shortlist fast. Let's run through them.

Okay, here's where egos get bruised and expectations get recalibrated. We see it constantly: someone shopping for their first toy grabs something 8 inches long and thick as a wrist because, well, go big or go home, right? Wrong. So wrong. A toy that's too big makes your body tense up. Tension is the opposite of pleasure. And a tense, uncomfortable first experience tends to put people off toys entirely — which is a shame, because the problem was never them. It was the size.

Let's break this apart. Length and girth are two completely different conversations. Most people fixate on length because it's the more dramatic number on the page. But girth — the diameter or circumference — is what you'll feel more intensely. An extra half-inch of width hits differently than an extra inch of length. When you're comparing products, spend at least as much time looking at the diameter measurement as the length.

A few shape details worth knowing. Tapered tips make a real difference during insertion, especially with firmer materials. That gradual narrowing lets your body open at its own pace instead of meeting a blunt edge. Ridges and textured surfaces add friction on every stroke, which feels amazing if you already know you're into that, but can be a lot if you're still figuring out what you like. Keep it smooth at first. And if you have any interest in anal play, listen closely: a flared base isn't optional. The rectum has no natural stopping point. A toy without a wide flared base can travel inside, beyond your reach, and that's an emergency room visit nobody wants to explain. Flared base, always. No debate.

Here's the truth nobody in a product listing will tell you: a 5-inch dildo that feels comfortable, that lets your body relax and respond, will give you a wildly better time than an 8-inch one that makes you clench and wince. You can always size up later once you know your body. You can't undo a bad first experience. Start kind. Start comfortably.

This is the decision that has the right answer. Type is a preference. Size is personal. Color is whatever makes you happy. But material? Material determines how your body interacts with that toy at a cellular level. Can bacteria hide inside it? Can you sterilize it fully? Will it irritate sensitive tissue over time? They're health questions. And the answers live in what the toy is made of.

Three materials sit at the top of the safety chart. All of them are non-porous, meaning the surface is completely sealed. Bacteria, mold, fungi — nothing gets in. And all three can be sterilized completely between uses.

If sex educators could pick one material to recommend for the rest of time, this would be it. Non-porous, hypoallergenic, and available in everything from marshmallow-soft to satisfyingly firm. It warms up to body temperature within minutes of being inside you, which gives it a natural, alive kind of feel that a lot of people love. One rule you need to memorize: silicone lube will wreck a silicone toy. It degrades the surface, makes it sticky, ruins the finish. Water-based lube only. Tattoo it on your brain.

Smooth. Hard. Precise. Glass feels completely different from silicone, and a lot of users (especially those who love G-spot or prostate stimulation) find that firmness hits spots that softer materials glide right past. It's also a dream for temperature play: run it under warm water for a heated, almost-melting sensation, or drop it in a bowl of ice water for a shivery cold that'll make your toes curl. Glass toys last basically forever with decent care. Just give it a quick look-over before each use. Any chip, any crack, any rough edge? Done. Retire it immediately.

Same safety profile as glass, with serious weight behind it. There's a gravity to steel toys (literally) that creates a deep, grounding internal pressure you won't get from anything lighter. Temperature play works beautifully here, too. And durability? These things are practically immortal. You'll hand it down to... actually, no, don't do that. But it will outlast everything else in your collection by decades.

TPE and TPR are soft, stretchy, affordable, and they feel really nice in your hand. They're everywhere in the toy market, and for good reason: the price point is accessible, and the texture is appealing. But they're porous. That means the surface has tiny openings where bacteria can settle in and set up camp, even after you wash thoroughly. You can't fully sterilize them, period. The move? Always use a condom over a TPE/TPR toy. And plan to toss it and grab a new one every 6 to 12 months if you're using it regularly. That's not fear-mongering — it's just honest upkeep. With a condom on, they're a totally reasonable choice, especially if you're on a budget.

PVC and jelly rubber often contain phthalates — chemical softeners linked to skin irritation and some longer-term health concerns. You can usually identify them before you even open the package: that strong, almost chemical smell, and a surface that feels sticky or tacky right out of the box. If you've already got one in your drawer, slap a condom on it, and it's usable. But if you're buying fresh? Spend a few extra dollars and get silicone. Your body deserves better than bargain-bin mystery chemicals.

Now for the part that's pure fun. How a toy looks doesn't change what it does physically, but it absolutely changes how you feel picking it up — and that headspace matters. The mood you bring to the experience shapes the experience itself.

On one end of the spectrum, you've got realistic: natural skin tones, anatomical detail, veins and all. Some people want that. It feels intimate, familiar, grounded in something recognizable. On the other end? Full-on fantasy. Dragons. Tentacles. Alien creatures. Designs that don't reference human anatomy at all and instead pull from mythology, sci-fi, or pure imagination. Fantasy dildos have blown up in popularity over the last few years, and not just as novelties. The craftsmanship on the best ones is absurd: hand-poured silicone with color gradients, sculpted textures, shapes that hit internal spots in ways conventional designs never would. They're art pieces that also happen to make you come.

Neither direction is "more serious" or "more legitimate" than the other. Want a lifelike replica? Great. Want a glittery purple dragon tongue? Also great. Grab whatever makes you grin when you see it. Whatever puts you in the mood before it even touches your body. That's the right choice.

If you've been reading along, you probably already have a pretty clear sense of what you want. You might not have realized it yet, but the instinct is there. This section is really just about confirming what your gut is already telling you.

Think about your goal. What does the ideal session look like in your head? Deep, filling penetration? Targeted, curl-your-toes G-spot pressure? Hands-free riding on a shower wall? Sharing something intimate with a partner? Your answer points you straight toward a type.

Now, be real with yourself about experience. Not where you'd like to be — where you are. If penetration is relatively new for you, a 5-inch, gently tapered silicone toy will teach you more about your own body and what turns you on than a massive beast ever could. There is absolutely no rush. Sizing up happens naturally as you learn what feels good and want to push a little further.

Pick your material next. If your budget allows it, go non-porous: silicone, glass, or steel. Your body (and your cleaning routine) will be happier for it.

Then size. Girth over length for most people. Tapered tip for easier entry. And comfort beats ambition every time. Every. Time.

Last step: compatibility. Planning on a strap-on? You need an O-ring compatible base. Any chance of anal play? Flared base, non-negotiable. Want it in the tub? Confirm waterproof ratings on anything with a motor.

Five decisions. Goal, experience, material, size, compatibility. That's the whole thing.

Five minutes of prep. That's all it takes. And the gap between "that was okay, I guess" and "holy shit, I need to do that again" almost always comes down to those five minutes.

Lube goes on first, and it goes on generously. Your body produces some natural lubrication, sure, but "some" isn't enough when you're introducing a toy. Water-based lube works with every material on the market. Silicone-based lube gives a longer-lasting slick feel and works great with glass and steel, but it will destroy a silicone toy over time. When in doubt? Water-based. Squeeze out more than you think you need. You can wipe away extra. Stopping mid-session because things got dry and uncomfortable is a mood killer.

Wash the toy before first use. Even if it just came out of a sealed package. Manufacturing residue, packaging dust, whatever. Warm water, mild unscented soap, rinse well, let it dry. Two minutes and you're done.

Go slow and stay tuned in to what your body is saying. Start with shallow penetration. Breathe. Let yourself adjust. If something hurts (actual pain, not just the unfamiliarity of a new sensation), stop. Add more lube. Try a different angle. Or put the toy down and come back to it another time. Pushing through discomfort doesn't make you tougher — it makes the experience worse and can cause real irritation or injury. Your body isn't an obstacle to overcome. It's the whole point. The more relaxed you are, the more sensation you'll feel, and relaxation only happens when you trust that you're setting the pace.

Taking care of your toys is easy. We're talking a few minutes after each session and some common-sense storage. That's it.

Non-motorized silicone, glass, and steel can handle the tough stuff: boiling in water for 3 to 5 minutes, a cycle on the top rack of your dishwasher (skip the soap), or a soak in a diluted bleach solution (10% bleach, 90% water) followed by a thorough rinse. Any of these fully sterilize the surface.

Toys with motors or electronics can't be submerged like that, even if they're labeled waterproof. Wipe them down with a toy cleaner or mild soap and warm water. Get into the seams and textured areas where stuff likes to hide.

TPE and TPR get warm water and mild soap only. No boiling. No bleach. Dry them completely before putting them away, because trapped moisture in a porous material is a bacteria party.

Storage: Give each toy its own breathable pouch — cotton, microfiber, the little satin bag it probably came with. Avoid sealed plastic bags (moisture gets trapped). Keep different materials separated. Silicone touching silicone is fine. Silicone stored against TPE? They can react and degrade each other's surface. A cool, dry drawer out of direct sunlight is all you need.

Replacement signals: Visible cracks or tears, a smell that won't wash off no matter what you do, discoloration, or a tacky/sticky surface that used to be smooth. For TPE/TPR, replace every 6 to 12 months with regular use, even if it still looks okay on the outside. For glass, even one tiny chip means it's done. Immediately. No second chances.

You've got the knowledge. Now go find the toy. If you already know what type you want, browse the category collections. If size is the thing on your mind, filter by that. If body safety is your top priority, the material-sorted collections will narrow it down fast. And if the look of a toy is what turns you on before anything else, start with theme or color and work backward from there. Your next click is right below.
