Quick answer
Choose a dildo shape and size based on your experience level and the sensation you want. Smooth tapers suit beginners, while textured or knotted shapes reward advanced users.
Why shape matters as much as size
A dildo's shape determines how it feels during insertion and movement. A tapered head eases entry, while a flared or bulbous head creates a pop sensation. Shaft texture — ribs, veins, scales — adds internal stimulation but can be intense for new users. Length and girth are obvious, but the profile (straight, curved, or knotted) affects which spots you reach and how the toy stays in place.
Material and firmness change the fit
Platinum silicone is body-safe, non-porous, and easy to clean. Within silicone, firmness varies. Softer silicone bends more, which can make a large toy feel more forgiving. Firmer silicone transmits texture more directly. If you're between sizes, a softer version of the next size up may work better than a rigid toy in your usual size.
How to choose your dildo shape and size
- Start with girth, not length: Measure the circumference of toys you already enjoy. Add no more than 1–1.5 inches (2.5–4 cm) in circumference for your next toy. Length matters less for most users.
- Match shape to your goal: For G-spot or prostate targeting, choose a curve or pronounced head. For depth play, pick a long, gradually tapering shaft. For fullness, look for a consistent or expanding girth.
- Consider texture tolerance: If you're new to texture, start with a smooth shaft and a single ridge or vein. Heavily textured toys (scales, knots, multiple rings) are best for intermediate or advanced users. Test texture with your fingers on the outside of the package before buying, if possible.
- Check the base: A flared base is essential for anal use and also helps with suction cup stability. Toys without a flared base are for vaginal use only or require a harness with a O-ring.
Real examples from the catalog
-
Nessus: Nessus has a thick vein running up his shaft leading to a flared head, plus a mid-point ring. The mid-point ring gives a tactile depth marker, so you feel exactly how deep you are — helpful if you're working on depth play.

Xaphan: Xaphan is covered in scales, ribs, veins and bulges, starting with a smooth tapered head. The smooth taper makes initial entry easier, but the textured shaft provides intense internal sensation once past the head — best for experienced users who want maximum texture.
