Buying your first dildo should be straightforward. In practice, it rarely feels that way. The options are overwhelming, the sizing information is often vague or contradictory, and it can be hard to know whether what you are looking at is genuinely good quality or just well-marketed.
This guide removes the guesswork. It covers every decision you need to make size, material, style, features, and budget in the order that actually matters, so your first purchase is something you will use and enjoy rather than something that sits in a drawer.
Start Here: The Decision That Matters Most
Before size, style, or price, the most important decision is material.
This matters first because it determines safety and because the sex toy market is largely unregulated, meaning products can be labeled "body safe" or "premium silicone" without those claims being verified by any external authority.
What to buy: Platinum-cured silicone, borosilicate glass, or stainless steel. These materials are non-porous bacteria and bodily fluids cannot penetrate the surface, which means they can be fully cleaned and sanitized after every use.
What to avoid: Jelly rubber, PVC, TPE, TPR, and anything labeled "silicone blend" or "skin-safe rubber." These materials are porous. They trap bacteria even after washing, may contain phthalates or other chemicals that leach onto sensitive tissue, and cannot be fully sanitized. Many budget realistic dildos are made from these materials regardless of what their packaging suggests.
The smell test: Genuine platinum silicone has almost no smell. A strong chemical or rubbery odor especially one that does not go away is a reliable sign of porous or chemically unsafe material.
The price signal: Platinum silicone costs more to produce. A realistic dildo priced at $15 to $25 is almost certainly not made from it. A low price combined with a "100% silicone" claim is a reliable red flag.
For a first dildo, platinum-cured silicone is the right choice. It is body-safe, easy to clean, skin-like in texture, and durable enough to last for years. All RealCock Toys dildos are made from platinum-cured silicone not blends, not TPE, not budget alternatives.
Choosing Your Size: The Most Common Beginner Mistake
Most first-time buyers either choose too large out of curiosity or guess randomly based on how a photo looks. Both approaches tend to produce the same result a dildo that gets used once and then stored.
The key principle: Start smaller than you think you need to. A size that feels comfortable and satisfying will get used regularly. A size that requires effort to insert will not.
What the numbers mean
Insertable length how much of the dildo can be used internally. This is always shorter than the total length listed, which includes the base, suction cup, or any external features. Always check insertable length specifically.
Diameter the width of the dildo at its widest point. This is the measurement that most affects how the dildo feels. Girth drives sensation more than length for most people, because the most sensitive nerve endings are concentrated in the first few inches of penetration.
Circumference the measurement around the outside. If a listing shows circumference rather than diameter, divide by 3.14 to convert.
Recommended beginner sizes
| Experience | Insertable Length | Diameter | Notes |
|---|---|---|---|
| Complete beginner | 4–5 in | 1.0–1.3 in | Slim, easy to manage |
| Most beginners | 5–6 in | 1.3–1.5 in | Realistic feel, manageable size |
| Some prior experience | 6–7 in | 1.5–1.8 in | Average / most popular range |
For most first-time buyers, 5 to 6 inches insertable length with a 1.3 to 1.5 inch diameter is the right starting point. It is substantial enough to feel realistic without being overwhelming.

Dildo Styles: Which Type Is Right for You?
Once you have material and size sorted, style is the next decision. Different designs serve different purposes.
Realistic Dildos
Designed to closely resemble real anatomy defined head, shaft texture, veining, and proportional shape. The lifelike detail makes them the most popular choice for beginners because the sensations are familiar and the transition to toy use feels natural.
Realistic dildos are the core of RealCock Toys' collection each handcrafted with anatomical detail and platinum silicone construction.
Smooth / Abstract Dildos
Simpler designs without realistic detail. Good for users who prefer straightforward stimulation without texture variation, or who find the realistic appearance less appealing. Often easier to insert because of the uniform profile.
Curved Dildos
Designed with an upward curve to direct stimulation toward the front wall of the vaginal canal where G-spot sensitivity is concentrated. If G-spot stimulation is a priority, a curved design will be significantly more effective than a straight one. See our G-spot dildo guide for more detail.
Suction Cup Base
A flat base that adheres to smooth, non-porous surfaces floors, walls, tiles, furniture. Allows hands-free use and opens up positions that are not possible with a hand-held dildo. Useful for beginners who want to explore positioning without needing a second hand. Many RealCock dildos include a suction-compatible base.
Vac-U-Lock Compatible Base
A more secure attachment system than a standard suction cup designed to connect to harnesses, sex machines, and dedicated mounts via a plug-and-socket mechanism. If you are planning to use a dildo with a harness or machine, choose a Vac-U-Lock compatible dildo from the start.
Vibrating Dildos
Include a built-in vibrator for additional stimulation. Adds a layer of sensation that many users find enhances orgasm. More complex to clean than non-vibrating options most are not boilable and require charging or battery replacement. A good second purchase once you know what size and shape works for you.
Features Worth Paying Attention To
Dual-density construction: A firm inner core with a softer outer layer mimicking the feel of real anatomy. This is the construction that produces the most realistic feel and makes a given size feel slightly more forgiving. Look for it if realism is a priority.
Encapsulated pigment vs. surface paint: Quality realistic dildos have color embedded throughout the material. Surface paint wears off with use and cleaning. Encapsulated pigment lasts indefinitely and does not create a surface layer that can separate.
Flared base: Essential for anal use. Any dildo intended for anal insertion must have a base wide enough to prevent it from traveling internally. Never use a toy anally that does not have a secure, flared base.
Seam-free construction: Visible seams on a dildo's surface can harbor bacteria and cause irritation during use. Seamless construction is a sign of quality manufacturing.
What You Need Alongside Your First Dildo
Lubricant non-negotiable. Lubricant reduces friction, makes insertion more comfortable, and protects both your body and the toy's surface. Use water-based lubricant with silicone toys silicone-based lubricants can degrade platinum silicone over time. Apply generously before insertion and reapply as needed.
Browse compatible water-based lubricants at RealCock Toys.
Storage a clean, dry pouch or bag protects your toy from dust between uses and prevents material contact with other toys. Store each toy separately. Keep away from direct sunlight and humidity.

How to Use Your First Dildo: Practical Starting Points
Clean before first use. Even a brand new toy should be washed with warm water and mild soap before its first use.
Start aroused. The body responds very differently to stimulation when fully aroused versus not. Spend time on external stimulation before any insertion this makes the experience significantly more comfortable and pleasurable.
Use more lubricant than feels necessary. First-time users almost always underestimate how much lubricant helps. Apply to both the toy and yourself.
Start with the tip only. Insert just the head and pause. Let your body adjust before going deeper. There is no benefit to full insertion on the first attempt sensation builds with time and relaxation.
Breathe slowly and deliberately. Pelvic floor muscles respond directly to breath. Slow exhales help them relax, which makes insertion significantly more comfortable.
Explore positions. Lying on your back with knees bent is the most manageable starting position. A pillow under the hips can help with angle. Once comfortable, explore other positions to find what works for your body.
Combine with external stimulation. Many people find that dildo use combined with clitoral or external stimulation produces stronger, more accessible orgasms than penetration alone. This is especially true for first experiences.
How to Size Up When You Are Ready
Once your first dildo feels consistently comfortable and you want to explore more, sizing up is straightforward but gradual.
The standard guideline is no more than 0.2 to 0.3 inches in diameter between your current comfortable size and the next purchase. In circumference terms, that is roughly 1 inch wider around.
The most popular size collection represents the natural next step for most users who have outgrown the beginner range. The standard 6–8" collection is a comfortable second milestone for experienced beginners.
Frequently Asked Questions
What size dildo should a complete beginner buy?
Start with 5 to 6 inches of insertable length and a diameter of 1.3 to 1.5 inches. This range feels realistic and satisfying while remaining manageable for a body adjusting to new sensations.
Is silicone always body safe?
No. Platinum-cured silicone is body safe. Tin-cured silicone, silicone blends, and materials marketed as "soft silicone" or "premium rubber" may not be. Look specifically for "platinum-cured silicone" on the product listing.
Do I need lubricant?
Yes, always. Lubricant makes insertion more comfortable, reduces friction that can cause irritation, and protects the toy's surface. Use water-based lubricant with silicone toys.
Can I use a dildo anally?
Yes, with the right toy. For anal use, the dildo must have a flared base to prevent it from traveling internally. Start at the smaller end of the beginner size range 1.0 to 1.3 inches diameter and use significantly more lubricant than for vaginal use.
How do I clean my dildo?
Wash with warm water and mild unscented soap after every use. Rinse thoroughly. Dry completely before storing. Platinum silicone toys can also be boiled or run through a dishwasher (top rack, no detergent) for full sterilization.
What if the size I chose turns out to be wrong?
If it feels too large: do not force it. Size down and try again. If it feels too small after a few sessions, size up by no more than 0.3 inches in diameter. Both are normal outcomes of a first purchase.
Final Thoughts
Buying your first dildo is a straightforward decision once you know what actually matters: material first, size second, style third. Get those three right and the rest falls into place.
Choose platinum-cured silicone. Start in the 5 to 6 inch range at a 1.3 to 1.5 inch diameter. Use water-based lubricant. Clean after every use.
