Shopping for fantasy toys can feel like learning a new language. Product pages mention knots, flares, sheaths, medial rings, nodules, tapered tips, and dual density silicone. Size charts list knot circumference, usable length, and base width. If you are new to this world, it is easy to feel lost before you even add something to your cart.
That is exactly why we created this guide. Think of it as your fantasy toy dictionary. We define the most common terms you will see while shopping, explain what each feature actually feels like, and share tips to help you decide which features suit you best. Because knots are one of the most searched and most misunderstood features, we also include a detailed knotting dildo guide covering what knots are, how they work, and how to enjoy them safely.
Keep this page bookmarked as you browse. When you are ready, explore our full Fantasy Dildos collection and put your new vocabulary to work.

Part 1: The Knotting Dildo Guide
Knots are one of the defining features of fantasy toys, so they deserve their own section. Here is everything you need to know.
Knot
A knot is a rounded, noticeably wider bulge along the shaft of a toy, usually located near the base. It is inspired by the anatomy of creatures in fantasy art, such as werewolves and certain dragons. The knot is typically the widest point of the insertable part of the toy.
What it feels like: A knot creates a strong feeling of fullness and pressure. Many people enjoy the sensation of the knot pressing against the entrance without fully inserting it.
Best for: Users who enjoy fullness and stretching, and who are comfortable with the circumference of the knot.
Knotted Dildo
A knotted dildo is any toy that includes one or more knots. Knotted designs range from subtle, gentle swells to dramatic bulges, so they suit many experience levels.
Knotting
“Knotting” refers to the act of inserting the knot fully past the entrance. It is often the goal for experienced users, but it is never required. Many people enjoy knotted toys without ever fully knotting.
Tie or Tied
In fantasy terminology, being “tied” describes the moment when the knot has been fully inserted and rests inside, creating a locked-in sensation. It is a fantasy term, and the feeling is simply the knot resting just past the entrance.
Pre-Knot or Bulb
Some toys feature a smaller swell above the main knot, called a pre-knot or bulb. It acts as a gentle warm-up before the wider knot.
Double Knot or Multi-Knot
A double-knotted or multi-knotted toy has two or more knots along the shaft, often increasing in size toward the base. These designs let you progress gradually from one knot to the next.
Inflatable Knot
An inflatable knot can be pumped up after insertion using a hand pump, so it starts small and grows to your preferred size. This is a great option for people who want the knot experience with more control. Learn more in our guide on how to use an inflatable dildo or browse our Inflatable Dildos collection.
Knot Circumference
This is the measurement around the widest point of the knot. It is the single most important number to check on any knotted toy, because it tells you how wide the knot really is.
How to Use a Knotted Dildo Safely
Knots are designed for gradual exploration, not instant results. Follow these tips:
- Check the knot circumference first. Compare it with the widest toy you already use comfortably.
- Use plenty of lube. Water-based lube is ideal for silicone. Browse toy-friendly options in our Lubricants collection.
- Enjoy the shaft first. Get comfortable with the rest of the toy before approaching the knot.
- Tease, do not push. Let the knot press gently against the entrance. Many people enjoy this pressure more than full insertion.
- Go slowly over many sessions. Knotting can take practice. There is no rush.
- Never force the knot. Pain is a signal to stop, not to push through.
- Remove slowly. If the knot is inserted, relax, breathe, add more lube, and ease it out gently.
- Use a flared base for anal play. A proper base prevents the toy from moving too far inside.
Are Knotted Dildos Good for Beginners?
Yes, as long as you pick a toy with a gentle knot that matches your comfort level. You do not need to use the knot at all to enjoy a knotted toy. Start with the shaft and let the knot be a future goal.
Part 2: Head and Tip Shapes
The head is the first part of the toy you experience, and its shape affects comfort more than almost anything else.
Tapered Tip
A narrow tip that gradually widens toward the shaft. Tapered tips make insertion easier and more gradual.
Best for: Beginners and anyone who wants a gentle start.
Pointed Tip
A narrower, more defined point at the very end. Similar to a tapered tip but more dramatic. Common on dragon and reptile-inspired designs.
Blunt Tip
A rounded or flat end without much taper. Blunt tips create more immediate pressure.
Best for: Experienced users who enjoy stronger sensation.
Flared Head or Crown
A head that widens noticeably before narrowing into the shaft, similar to the glans on realistic toys. The flared edge, sometimes called a crown or ridge, creates a distinct sensation with movement.
Spade Head
A flattened, wider head shaped somewhat like a spade. Found on some creature designs. It creates a broad feeling of pressure.
Ridged Head
A head with raised rings or edges around it. Adds texture from the very first moment.
Part 3: Shaft Textures and Features
The shaft is where most of the fantasy personality lives. Here are the textures you will see most often.
Ridges
Raised lines or bands that wrap around the shaft. Ridges create a pulsing sensation as the toy moves. Soft, rounded ridges feel gentle. Sharp, deep ridges feel intense.
Rings
Similar to ridges but usually evenly spaced and more uniform. Rings create a steady, rhythmic texture.
Medial Ring
A single, thicker ring located partway along the shaft, often inspired by equine or centaur anatomy in fantasy art. It adds a noticeable point of pressure in the middle of the toy.
Scales
Small overlapping textures that mimic reptile or dragon skin. Scales range from subtle patterns you barely feel to raised details that add real sensation.
Best for: Dragon lovers who want authentic detail. Our bestsellers like Ashryn The Phoenix Reborn showcase how silicone can capture intricate creature detail.
Veins
Raised lines that run along the length of the shaft. Veins are common on both realistic and creature designs and add subtle texture.
Nubs or Nodules
Small raised bumps scattered across the surface. Nubs add a tingling, textured sensation.
Soft Spines or Barbs
Flexible, rounded protrusions inspired by alien or feline creature designs. On body-safe toys, these are always soft and flexible, never sharp. They add a unique, fluttering texture.
Bulges
Swollen sections along the shaft that are wider than the areas around them. Bulges differ from knots because they can appear anywhere on the shaft, not only near the base.
Tentacle Texture
A long, tapering, often twisting shape inspired by sea creatures, sometimes decorated with suction-cup-style details along one side.
Spiral or Twist
A shaft that twists along its length. Spirals create a rotating sensation with movement.
Curve
A gentle or pronounced bend in the shaft. Curved toys are often designed to target internal pleasure points more easily.
Sheath
A textured layer at the lower part of the shaft, inspired by creature anatomy where the shaft emerges from a protective sheath. On a toy, the sheath often forms a wider, textured section near the base.
Part 4: Base Designs
The base affects safety, stability, and how you can use the toy.
Flared Base
A base that is significantly wider than the shaft. A flared base is essential for anal play because it prevents the toy from traveling too far inside the body.
Suction Cup Base
A base with a smooth, flat, slightly concave underside that sticks to smooth surfaces like glass, tile, or finished wood. Great for hands-free play.
Harness Compatible
A toy with a base shape that fits standard strap-on harnesses. Check the product details to confirm compatibility.
Platform Base
A wide, flat base designed to sit stably on a surface. Useful for riding positions.
Balls or Testicles
A sculpted scrotum-style feature near the base. It adds realism, gives you something to grip, and can act as a natural stopper.
Sheath Base
A base that forms part of the sheath design, creating a textured, wider foundation for the shaft.
Part 5: Measurement and Sizing Terms
Understanding measurements helps you choose the right size with confidence.
Total Length
The full length of the toy from tip to base, including decorative bases and flares.
Usable Length or Insertable Length
The length that can be comfortably inserted, not counting the base. This is more useful than total length.
Circumference or Girth
The measurement around the toy. Circumference is often more important than length for comfort.
Diameter
The measurement straight across the toy. Diameter is useful, but circumference gives a better picture of irregular shapes like knots and ridges.
Widest Point
The largest circumference on the insertable part of the toy. On knotted toys, this is usually the knot.
Knot Circumference
The circumference at the widest part of the knot. Always check this number on knotted designs.
Base Width
How wide the base is. A wider base offers more stability and safety.
Size Tiers
Many fantasy brands offer designs in multiple sizes, such as small, medium, large, and extra large. Sizes vary from brand to brand, and even from design to design, so always check the actual measurements rather than relying on the label.
Part 6: Firmness and Material Terms
Soft Firmness
Very flexible and squishy. Soft toys are forgiving and comfortable, especially for larger sizes.
Medium Firmness
A balance of flexibility and structure. Many people consider medium firmness the sweet spot.
Firm
A toy that holds its shape with little flex. Firm toys deliver more precise, intense pressure.
Dual Density
A toy made with two layers of silicone: a firmer inner core and a softer outer layer. Dual density toys feel soft on the surface but have enough structure for control.
Shore Hardness
A technical scale used to measure how soft or firm a material is. Some brands list shore hardness on product pages. In general, a lower number means a softer toy.
Body-Safe Silicone
A nonporous, phthalate-free material that can be fully cleaned. It is the gold standard for toys. Learn more in our guide to body-safe silicone sex toys.
Platinum-Cured Silicone
Silicone set using a platinum catalyst. It is known for purity and durability and is considered a premium material for intimate products.
Nonporous
A sealed surface that does not absorb fluids or bacteria. Nonporous toys can be fully sanitized.
Part 7: Color and Finish Terms
Fantasy toys are as much about looks as feel. Here are the color terms you will see.
Marbled
Two or more colors swirled together in a stone-like pattern. Each marbled toy is unique. See Aria The Marble Muse for a stunning example.
Gradient or Fade
Colors that blend smoothly from one shade to another, often from tip to base.
Color-Changing
Silicone that shifts color with temperature, usually becoming lighter or changing hue as it warms to body temperature.
Glow in the Dark
Silicone that absorbs light and glows softly in the dark.
UV Reactive
Silicone that glows brightly under black light.
Metallic or Pearlescent
A shimmering finish created with body-safe pigments.
Solid Color
A single, even color throughout the toy.
Hand-Poured
A toy made by pouring silicone into the mold by hand, often in layers. Hand-poured designs have subtle variations that make each one one of a kind.

- Use your fingers or a soft brush on every texture.
- Pay special attention to the area around the knot and base.
- Rinse thoroughly and dry completely.

Frequently Asked Questions
What is a knot on a dildo?
A knot is a rounded, wider bulge on the shaft of a toy, usually near the base. It is inspired by fantasy creature anatomy and creates a strong feeling of fullness. It is typically the widest part of the insertable section.
Do I have to insert the knot?
No. Many people enjoy knotted toys without ever fully inserting the knot. The pressure of the knot against the entrance can be enjoyable on its own. Knotting is an optional goal that can take practice.
What is the difference between a knot and a bulge?
A knot is usually located near the base and is often the widest point of the toy. A bulge is a swollen section that can appear anywhere along the shaft and is usually less dramatic than a knot.
What does dual density mean?
Dual density means the toy has two layers of silicone: a firmer inner core and a softer outer layer. This gives a soft surface feel with enough structure for control.
What is the most important measurement on a knotted toy?
Knot circumference is the most important measurement, because it tells you how wide the widest part of the toy really is. Compare it to toys you already use comfortably.
Final Thoughts
Fantasy toys are full of unique features, and understanding the vocabulary makes shopping easier, safer, and more exciting. When you know what a knot, flare, medial ring, or dual density design really means, you can choose a toy that matches your comfort, your preferences, and your imagination.
Use this knotting dildo guide and glossary as your reference whenever you browse. Remember the essentials. Check the knot circumference. Start with gentle features and progress gradually. Choose a flared base for anal play. Use plenty of water-based lube. And never force a knot.
