Choosing a dildo is more personal than most sex toy purchases. Unlike vibrators, where motor strength and pattern variety do most of the work, a dildo’s payoff comes almost entirely from shape, size, and the way it feels in your hand and your body. Get those three things right and almost everything else is secondary. Get them wrong and even an expensive toy sits in a drawer.
This list covers five picks across different use-cases: a beginner-friendly realistic model, a textured novelty option, a glass choice for temperature play, and two sex machine attachments for people who want hands-free or partnered experiences. Each one has been editorially assessed based on manufacturer specifications, aggregated user reviews, and material safety data. No spec-based review lab testing claimed.
If you want to go deeper on any individual product, we have full reviews of the Sweet Breeze Dildo Pink, the Faultless Dildo by ClearLust, and the Fuck Me Harder Sex Machine Attachment 1 Ripple Dildo linked throughout. For anal-specific picks, see our Best Anal Toys for Beginners guide instead.
What actually matters when you’re choosing a dildo
Most buying guides overload you with features. Realistically, four things determine whether a dildo works for you.
Material and body safety
The FDA does not regulate adult toys as medical devices, which means anything can be sold as “body safe” without independent verification. In practice, three materials are genuinely safe: platinum-cure silicone, borosilicate glass, and medical-grade stainless steel (316L). All three are non-porous, meaning bacteria cannot work their way into the material between uses. They can also be fully sterilised, not just rinsed.
TPE and jelly rubber are the materials to avoid. Both are porous, both degrade over time, and both can leach chemical compounds. If a product listing does not specify the exact silicone grade or glass type, treat it with caution.
Size: shaft diameter matters more than length
Length is visible and easy to compare, so most product listings lead with it. But diameter is what most people actually feel. A shaft that is 1.25 inches (3.2 cm) in diameter is noticeably fuller than one at 1.0 inch (2.5 cm). If you are buying your first dildo, start at the lower end of the diameter range and move up from there. Injuries from oversizing are more common than most buyers expect: U.S. emergency room data cited by innerbody.com puts dildo-related injuries above 1,000 per year.
A tapered tip makes entry easier. A bulged or ridged shaft creates a different kind of stimulation than a smooth one. Neither is better in the abstract; it depends entirely on what you want to feel.
Base design: suction cup, flared, or flat
A suction cup base sticks to smooth surfaces and frees both hands, which is useful for solo use, harness play, or mounting on a sex machine. A flared base is the minimum requirement for any anal use. A flat or rounded base with no flare is fine for vaginal use but should never go anywhere near the rectum.
Sex machine attachments, like the Fuck Me Harder Sex Machine Attachment 2 Pink Dildo or the more adventurous Fuck Me Harder Sex Machine Attachment 3 Fantasy Dildo, use a different mounting system entirely: they connect to a machine’s drive arm rather than using a suction cup, so compatibility with your specific machine matters before you buy.
Texture and shape: realistic vs. abstract
Realistic dildos, modelled on a penis with a defined glans and veining, are the most intuitive for most people. They are also the safest starting point if you are unsure what you prefer. Abstract or textured designs (ridges, spirals, novelty shapes) can deliver more intense stimulation but tend to suit people who already know they want texture. If you are curious about non-realistic shapes, the reviews of the Faultless Dildo by ClearLust are a good place to gauge what users with similar preferences found.

Who should skip a dildo entirely
A dildo is not the right first toy for everyone. If you are new to penetration and nervous about sensation, a small external vibrator or a finger-sized insertable vibrator may be a better entry point, simply because vibration creates arousal that makes penetration easier. A non-vibrating dildo requires you to arrive at a level of arousal on your own before insertion feels comfortable.
Equally, if you are primarily interested in anal play, the products on this list are not all designed for that purpose. Head to Best Anal Toys for Beginners for options with the flared bases and tapered shapes that anal play specifically requires.
For those who enjoy bondage or restraint as part of play, pairing a hands-free suction-cup dildo with restraints can be a natural combination. Our Best Beginner Bondage Gear guide covers that territory.
How to actually use a dildo: technique over instinct
Most guides skip this part. They list products and materials and move on, as if knowing what to buy automatically translates into knowing what to do with it. It does not, and that gap is where a lot of people end up frustrated with an otherwise good toy.
The most common mistake is rushing penetration. Arousal increases blood flow to vaginal tissue, which causes natural lubrication and, more importantly, causes the vaginal canal to lengthen and the cervix to lift. That process takes time, typically 15 to 20 minutes of stimulation for most people. Inserting a dildo before that process is complete is uncomfortable regardless of how good the dildo is. Use external stimulation first.
Apply lube generously, even if you are already aroused. A water-based lubricant on a silicone toy reduces friction at the point of entry significantly, and the difference is noticeable. Start with the tip only, let the body adjust, and add depth incrementally. There is no award for going faster.
Finding the right angle
Angle changes everything. For vaginal use, tilting the shaft slightly upward toward the navel targets the front wall of the vagina, where the greatest concentration of nerve endings sits. A curved dildo, like a specifically G-spot-oriented design, does this passively. A straight shaft can do it too, but you control the angle manually.
For people who find that straight in-and-out thrusting does not do much, try a rocking motion instead: insert to a comfortable depth and rock the base forward and back rather than pulling out and pushing in. This changes which part of the shaft contacts the internal walls and often produces more consistent stimulation.
Suction cup positioning
If you are using a suction cup dildo on a flat surface, wall mounting tends to work better for standing use if the surface is smooth tile or similar. For floor or furniture mounting, apply firm downward pressure and give it a half-twist to create a proper seal before you rely on it for leverage. A suction cup that fails mid-use is not dangerous, but it is disruptive and usually happens because the surface had slight moisture or texture that prevented a full seal.
Cleaning and storage: the part most buyers underestimate
Body-safe materials are only body-safe if you maintain them correctly. The good news is that platinum-cure silicone, borosilicate glass, and stainless steel are genuinely easy to clean once you know the method.
For silicone dildos without a motor (which none of the dildos on this list have, so all five qualify), the fastest sterilisation method is boiling. Submerge in boiling water for three minutes. That kills bacteria and eliminates residue that soap alone can miss. Alternatively, run them through the top rack of a dishwasher without detergent. Both methods work.
Glass and steel can be boiled, dishwashed, or cleaned with a 10% bleach solution followed by a thorough rinse. Glass should be inspected before each use for chips or cracks. A hairline crack that you cannot see can cause small lacerations internally, so when in doubt, replace it.
TPE toys require a different approach because they cannot be sterilised, only cleaned. Warm water and mild soap after every use, and replace them every six to twelve months even with consistent cleaning. Using a condom over a TPE toy for shared use is the safer approach and also extends the toy’s usable life slightly.
Storage basics
Store silicone toys separately from each other. When two silicone items are in direct contact for extended periods, surface degradation can occur, particularly with lower-grade formulations. A cotton pouch or the original packaging works fine. Glass and steel are less fussy about contact but should be stored where they cannot roll off a surface and chip.
Avoid storing any toy in an airtight plastic bag for long periods. Trapped moisture encourages bacterial growth even on non-porous materials.
Sex machine attachments: what to know before buying
Sex machine attachments function differently from standard dildos and are worth addressing separately because the buying considerations are not the same.
The primary factor is connector compatibility. Most consumer-grade sex machines use one of two systems: a universal Vac-U-Lock style fitting or a machine-specific threaded connector. The Fuck Me Harder Sex Machine Attachment 1 Ripple Dildo and its siblings in that line are designed for a specific machine. Before buying any attachment, confirm that the fitting matches your machine’s drive arm. Adapters exist but add play (looseness) to the connection, which changes the feel.
Stroke length and speed settings on the machine determine how much of the attachment’s length you actually experience. A machine set to a short stroke with a long attachment means you are only using the first two or three inches regardless of overall length. Match your machine’s stroke range to the part of the attachment where the texture or curve is concentrated.
Lubrication matters even more with a machine than with manual use because the mechanical repetition creates more friction, more quickly. Reapply water-based lubricant every few minutes during use rather than applying once at the start.
Realistic vs. abstract: how to decide
This is the question most buyers circle back to, and the honest answer is that it depends more on psychology than anatomy.
Realistic dildos work well for people who find familiar shapes easier to get comfortable with, or who want the toy to approximate partnered sex. They also tend to be more intuitive positionally because the defined glans gives you a clear sense of orientation without looking.
Abstract or fantasy shapes suit people who find realistic aesthetics distracting, or who want stimulation that is explicitly different from what a partner provides. Ridged or spiral designs create a different sensation profile on insertion and withdrawal, and some users find that texture sustains stimulation more effectively than a smooth shaft during extended use.
If you genuinely cannot decide, a smooth-shafted realistic model is the lower-risk starting point. You can always add texture in a future purchase once you know what you are working with.
Common questions from first-time buyers
How do I know if a dildo is the right size for me?
Measure what you already use comfortably, whether that is fingers or a previous toy, and compare the diameter. Two fingers side by side average roughly 1.1 to 1.3 inches (2.8 to 3.3 cm) in diameter for most adults. Starting at or slightly below that diameter and building up is a reliable approach.
Can I use a dildo during partnered sex?
Yes, and many people do. A suction-cup dildo mounted to a wall or furniture creates a stable hands-free setup that works alongside a partner. Double-ended dildos designed for simultaneous penetration are a separate category with their own sizing considerations.
Do I need a harness for strap-on use?
Most harness-compatible dildos have a flat flange at the base that sits against an O-ring harness. Not every dildo on this list is harness-compatible, so check the base design if strap-on play is your intended use. A suction-cup base is generally not harness-compatible because the cup adds too much bulk behind the harness panel.
How long do silicone dildos last?
With proper cleaning and storage, a quality platinum-cure silicone dildo should last several years without material degradation. The signs that a silicone toy needs replacing are tackiness on the surface, a persistent odor that cleaning does not remove, or visible discoloration that is not surface residue. Any of those is a signal to replace, not continue using.
