Shopping for your first dildo can feel overwhelming when you're staring at hundreds of options in every shape, size, color, and material imaginable. But here's the thing: choosing the right one is much simpler than it looks once you know what factors actually matter. Size, material, shape, and intended use will narrow things down faster than you think.
In this guide I'll walk you through everything you need to know to make a confident, informed choice that works for your body and your pleasure. Whether you're buying your first toy or looking to add something new to your collection, the goal is the same: find something that genuinely fits your needs and feels good to use.
A dildo is an insertable sex toy designed for penetration, whether vaginal, anal, or both. Unlike vibrators, dildos don't rely on a motor to deliver pleasure. They work through shape, size, texture, and movement, giving you complete control over the experience. You thrust, you angle, you set the pace. That simplicity is exactly what makes them so versatile and so popular across all genders and relationship styles, whether you're playing solo or with a partner.
Now, the line between dildos and vibrators isn't always perfectly clear. Some dildos do have a vibration function built in, and some vibrators are shaped for penetration. The difference that actually matters is intent and design. If the toy is built primarily for insertion and manual stimulation, it's a dildo. If the motor is the main event, it's a vibrator. Knowing that distinction helps you shop with a lot more confidence.
One of the biggest myths in the dildo world is that bigger is always better. It isn't. The right size is the one that feels good in your body, and that looks different for everyone. If you're new to penetration, a good starting point is thinking about how many fingers feel comfortable during solo play. That gives you a realistic baseline for girth without any guesswork.
When it comes to size, length and girth are two separate decisions worth thinking about independently. Girth determines how full you feel, while length affects how deep the stimulation goes. Most beginners find that girth matters more than length, since you don't have to insert a toy all the way to enjoy it. Start smaller than you think you need. Your body will tell you exactly where to go from there.
Choosing a dildo material isn't just about how something feels. It's a health decision. The material determines whether a toy is easy to clean, whether it can harbor bacteria, and whether it contains chemicals you really don't want inside your body. It's worth taking this part seriously before anything else, because no amount of great shape or size makes up for a toy that isn't body-safe.
The three materials I always recommend are medical-grade silicone, glass, and stainless steel. Medical-grade silicone is non-porous, hypoallergenic, and comes in a range of firmness levels from soft and flexible to quite firm. Glass and stainless steel are smooth, incredibly easy to sterilize, and perfect for temperature play since they respond quickly to warm or cool water. All three are long-lasting investments that will serve you well with proper care.
What you want to avoid are porous materials like jelly, rubber, and PVC. These can contain phthalates, which are chemicals used to soften plastics and are not something you want in contact with your mucous membranes. Porous toys also trap bacteria no matter how well you clean them. One more thing worth knowing is that silicone-based lubricants can degrade silicone toys over time, so if your dildo is silicone, always reach for a water-based lube instead.
Shape is one of those things that looks like a purely visual choice but is actually deeply functional. The curve, the tip, the texture, the base — every design decision is there for a reason. Once you understand what each feature is meant to do, shopping becomes a lot more intuitive and a lot less overwhelming.
Straight dildos are great for consistent depth and straightforward thrusting, while curved ones are designed with specific anatomy in mind. A pronounced upward curve helps target the G-spot in people with vaginas, and the same principle applies to prostate stimulation in people with penises. If internal pleasure is your goal, a gentle to moderate curve is often worth prioritizing over a perfectly straight shaft. Textured options, like ribbed or bumped surfaces, add friction and varied sensation with every movement, which many people find intensifies the experience significantly.
If you're planning to use your dildo for anal play, there is one rule that is non-negotiable: the toy must have a flared base. Unlike the vaginal canal, the rectum has no natural stopping point, and a toy without a secure base can travel further than intended. A flared base keeps everything safe and in control, so you can focus entirely on the pleasure side of things.
How you plan to use your dildo is honestly the most practical filter you have when narrowing down your options. If you're playing solo and want hands-free fun, look for a toy with a suction cup base. You can attach it to a smooth surface like a shower wall or a hard floor and enjoy a completely different kind of experience. If you're shopping with a partner in mind, a double-ended dildo lets both of you enjoy penetration at the same time, which opens up a whole new dynamic in shared play.
For strap-on use, harness compatibility is the detail you can't overlook. You need a dildo with a flared base that fits securely into your harness's O-ring, so always check the diameter of the base before buying. If you're exploring anal play, revisit the shape and size considerations from earlier and go smaller than you think you need, especially if you're a beginner. Thinking through your use case before you shop saves you a return and gets you to the good part a lot faster.
Whether you want your dildo to look like a penis or nothing like one at all is entirely a personal choice, and neither option is more legitimate than the other. This comes down to aesthetics and what feels right for you mentally and physically. It has no bearing on the quality of the toy or the pleasure it can deliver, so try not to overthink it.
Realistic dildos are designed to closely mimic the look and feel of a penis, often with detailed texture, a defined head, and sometimes even a sculpted base. Many people find that visual realism adds to the experience, especially during solo play or when used with a partner. They tend to come in a wide range of skin tones and sizes, so there's a lot of variety within the realistic category alone.
Non-realistic dildos take a completely different approach. They might be sleek and smooth, boldly colored, made from glass with a sculptural shape, or designed with curves and textures that have nothing to do with anatomy. These options are just as pleasurable and often feel less intimidating for first-time buyers. If you're not sure where to start, a non-realistic design in a material you trust is almost always a solid first move.
No matter which dildo you choose, lubrication is non-negotiable. Your body will thank you for it every single time. For silicone toys, always use a water-based lube since silicone-based formulas can break down the material over time and make it harder to clean properly. Glass and stainless steel are compatible with all lube types, which gives you a bit more flexibility. When in doubt, water-based is the safest and most versatile choice across the board.
Caring for your dildo properly is what makes it last. A well-maintained toy made from body-safe materials can serve you for years, which makes the initial investment more than worth it. Clean it after every single use, store it somewhere cool and dry, and check it regularly for any signs of wear. If the surface starts to feel sticky, tacky, or looks discolored, it's time to replace it.
When you're figuring out how to choose a dildo for the first time, spending a lot of money upfront is not necessary. A reliable, body-safe first dildo can be found in the $30 to $60 range without compromising on material quality or safety.
Medical-grade silicone options exist at accessible price points, so you don't have to choose between protecting your body and protecting your wallet. The most important thing is that the toy is made from a non-porous, phthalate-free material, regardless of what it costs.
Think of your first purchase as a learning experience rather than a definitive answer. You're gathering information about what your body enjoys, what size feels right, what shape works for you. That knowledge is genuinely valuable and will make every future purchase sharper and more satisfying. Start simple, start safe, and let your experience guide you from there. Life is too short for bad sex, and it's also too short to wait until you have the perfect budget to start exploring.
