Choosing your first dildo comes down to four decisions: size, material, shape, and whether you want a realistic feeling dildo or a smooth, non-representational design. For most beginners, the safest starting point is a body-safe silicone dildo in the 4–6 inch insertable range, with a gentle curve and a flared base. Smaller dimensions reduce discomfort, medical-grade silicone is non-porous and hypoallergenic, and the flared base makes the toy safe for any kind of play. Everything else — vibration, suction cups, harness compatibility — is a preference layer on top of those four core choices.

Why your first dildo matters more than you think
A first toy that fits your body and your comfort level is the difference between a positive experience and one that gets shoved into a drawer. The most common reason beginners return their first toy isn't quality — it's that they bought something too big, too firm, or made from a material their body didn't tolerate. About 60% of first-time buyers underestimate how much smaller a beginner-friendly toy should be compared to what they imagine wanting.
This guide walks you through every decision in the order it actually matters, so you can shop with confidence the first time.
Step 1: Choosing the right size for a beginner dildo
The short answer: start with a small beginner dildo in the 4–5 inch insertable length and 1–1.25 inch diameter range. You can always size up later. Sizing down after buying too big is a more expensive lesson.
How dildo sizing actually works
There are two numbers that matter, and most product listings show both:
- Insertable length — the part that actually goes inside, measured from the tip to where the shaft meets the base. This is the number you care about.
- Total length — includes the base or balls. Not relevant to fit.
- Diameter (or girth) — measured across the widest point of the shaft. For most people, girth affects comfort more than length does.
Recommended starting sizes by experience
| Experience Level | Insertable Length | Diameter |
|---|---|---|
| Complete beginner | 4–5 inches | 1–1.25 inches |
| Some experience | 5–6 inches | 1.25–1.5 inches |
| Comfortable & ready to size up | 6–7 inches | 1.5–1.75 inches |
About the "7 inch dick" question
A 7 inch dildo is one of the most-searched sizes online, mostly because it matches the average size people assume is "standard." In reality, research consistently puts average erect length closer to 5.1–5.5 inches. A 7 inch insertable toy is firmly in the intermediate-to-advanced category — not because anyone "can't handle it," but because going from zero to seven is rarely comfortable. If 7 inches is your eventual goal, start with 5 inches and progress gradually. Most people who do this find they prefer something in the 6 inch range anyway.
Step 2: Material — the safety decision most beginners skip
Material matters more than shape, color, or any feature. A toy made from the wrong material can cause irritation, infection, or absorb bacteria you can't wash out. There are only two materials a beginner should consider:
Platinum-cured silicone (the gold standard)
Medical-grade or platinum-cured silicone is non-porous, hypoallergenic, phthalate-free, and tolerates boiling water for sterilization. It's the only material backed by ISO 10993 biocompatibility testing for prolonged body contact. It's also more expensive — expect $40 and up for a quality silicone dildo — but it lasts for years and is the only material truly safe to share or use without a condom. All RealCockx realistic dildos are made from 100% platinum-cured silicone for this reason.
Glass or stainless steel
Both are completely non-porous, totally body-safe, and easy to sterilize. They're firmer than silicone (which some beginners actually prefer for control) and excellent for temperature play. The downside: less forgiving on first use because they don't flex.
Materials to avoid as a beginner
- Jelly, rubber, PVC, vinyl — porous, often contain phthalates, can degrade other toys when stored next to them. Cheap for a reason.
- TPE/TPR — soft and realistic-feeling, but porous and impossible to fully sanitize. Has a use-life of months, not years.
- "Skin-safe" with no specific material listed — this is a marketing phrase, not a safety standard. Always look for explicit material disclosure.
If a product page won't tell you exactly what the toy is made from, that's your answer about whether to buy it.
Step 3: Shape — realistic vs. smooth
Once you've locked in size and material, the next question is what shape and texture you want.
Realistic feeling dildos
A realistic feeling dildo is sculpted to look and feel like an actual phallus — defined head, visible veins, dual-density silicone (firmer core, softer outer layer that mimics real skin texture), and natural skin tones. The appeal isn't just visual; the sculpted head provides additional internal stimulation that smooth toys don't. Dual-density silicone in particular has become the standard for realistic toys because it pairs the squish of real skin with the structural firmness needed for actual use. RealCockx's Sliding-Skin collection uses a three-layer construction that takes this concept further with a movable outer skin layer.
Choose realistic if: you want a lifelike experience, you're shopping with a partner and want something that looks like the real thing, or you specifically enjoy the texture of a defined head.
Smooth, non-representational dildos
These are sleek, often colorful, and shaped for ergonomics rather than realism — gentle curves designed to hit specific internal spots (the G-spot or prostate), tapered tips for easy entry, sometimes textured shafts.
Choose smooth if: you want something discreet, you're drawn to design rather than realism, or you specifically want G-spot or prostate-targeted stimulation.
What about color?
Purely preference. Realistic toys come in a range of skin tones; non-realistic toys come in every color. There's no functional difference.
Step 4: Base — the feature nobody mentions until it's too late
Every dildo for a beginner should have a flared base — a wide flat bottom that prevents the toy from going further than intended. This is non-negotiable for any kind of anal play and a generally smart safety feature regardless of how you plan to use it.
A flared base also gives you three bonus features:
- Suction cup compatibility — many flared-base dildos stick to flat surfaces for hands-free use.
- Harness compatibility — if you want to use the toy with a strap-on harness now or later, you need a flared base.
- Stability — easier to grip and control.
Step 5: Features to consider (and which to skip on round one)
Worth considering
- Suction cup base — versatile and useful even if you don't think you'll use it now.
- Slight curve — better for G-spot or prostate access than a perfectly straight shaft.
- Tapered tip — easier entry, especially for new users.
Skip on your first toy
- Vibration — adds cost and complexity; you'll learn faster what you like without it.
- Thrusting or rotating mechanisms — intermediate features. Master the basics first, then explore.
- Anything with a remote or app — same logic.
- Extreme textures (ribs, bumps, multiple heads) — these are preference-specific. Get a baseline first.
You can always upgrade to a more featured toy later. Almost everyone who buys a feature-loaded toy as their first one ends up wishing they'd started simpler.
Step 6: Budget — what to actually expect to spend
- Under $25 — almost always TPE or jelly. Skip.
- $25–40 — entry-level silicone. Often single-density, basic shape, but body-safe. Reasonable starting point.
- $40–80 — the sweet spot for a first toy. Quality silicone, often dual-density, well-finished. This is what most people should buy.
- $80–150+ — premium brands, dual-density realistic toys, designer pieces. Worth it once you know what you like.
A good silicone dildo lasts 5+ years with proper care. Per use, the $60 toy is dramatically cheaper than the $20 one you replace every six months.
Step 7: Using your first dildo safely
Three rules that handle 90% of beginner mistakes:
- Use lube. More than you think. Water-based lube is compatible with all materials. Silicone lube degrades silicone toys, so avoid it with a silicone dildo.
- Go slowly. Your body needs time to adjust. Rushing is the single biggest cause of discomfort.
- Clean before and after every use. Warm water and unscented soap for silicone. Boiling water or a 10% bleach solution for full sterilization (silicone only, not motorized toys).
A practical shopping checklist
Before you click buy, the product page should clearly state:
- ✅ Specific material (look for "100% platinum silicone" or "medical-grade silicone")
- ✅ Insertable length (not just total length)
- ✅ Diameter at the widest point
- ✅ Whether it has a flared base
- ✅ Cleaning and storage instructions
- ✅ Return/satisfaction policy (important for an item you can't try first)
If any of these are missing, ask the seller before ordering — or move on.

Frequently asked questions
What size dildo should a beginner start with?
A beginner should start with a dildo in the 4–5 inch insertable length range and 1–1.25 inch diameter. This size is comfortable for first-time use and lets you assess what feels good before sizing up. Most people end up preferring the 5–6 inch range long-term, but starting smaller is the safest path to that conclusion.
Is a 7 inch dildo too big for a beginner?
Yes, in most cases. A 7 inch insertable dildo is an intermediate-to-advanced size. The average erect penis length is approximately 5.1–5.5 inches, so 7 inches is well above what most bodies are used to. If 7 inches is your goal, start with 5 inches and progress gradually.
What's the safest material for a first dildo?
Platinum-cured medical-grade silicone is the safest material for a first dildo. It's non-porous, hypoallergenic, phthalate-free, easy to sterilize, and tested under ISO 10993 standards for biocompatibility. Glass and stainless steel are also fully body-safe alternatives. Avoid jelly, rubber, PVC, vinyl, and TPE/TPR for body-contact toys.
What is a realistic feeling dildo made of?
A realistic feeling dildo is typically made from dual-density silicone — a firmer inner core wrapped in a softer outer silicone layer that mimics the texture and squish of real skin. High-quality realistic dildos use platinum-cured silicone for both layers, which keeps the toy fully body-safe while delivering a lifelike feel.
How do I clean a silicone dildo?
Wash a silicone dildo with warm water and unscented soap before and after each use. For full sterilization, you can boil a non-motorized silicone toy for 3–5 minutes, run it through the top rack of a dishwasher without detergent, or wipe it with a 10% bleach solution and rinse thoroughly. Never boil or submerge a motorized toy.
Do I need lube with a dildo?
Yes. Water-based lube is recommended for all dildos and is compatible with every material. Silicone-based lube should not be used with silicone toys because it degrades the surface over time. Oil-based lubes work with glass and stainless steel but not silicone.
What's a small beginner dildo?
A small beginner dildo typically measures 3–5 inches in insertable length and under 1.25 inches in diameter. These dimensions are sized below average for easy use during initial sessions and are particularly recommended for anyone new to internal stimulation or returning after a long break.
