Quick answer

To choose a custom dildo, first decide on the shape that matches your intended use—gradual taper for exploration, pronounced ridges for targeted stimulation—then pick a size that is comfortable but slightly challenging, and select a firmness that balances sensation with comfort.

Why shape matters more than length

A dildo's shape determines how it feels during use and which areas it stimulates. Straight shafts are predictable and good for beginners, while curved designs target the G-spot or prostate. Spiraled or textured shapes add variety but require more control.

Custom dildos let you choose specific contours. For example, a gradual taper allows you to ease into deeper penetration, while a bulbous head provides a distinct pop sensation. Consider whether you prefer gentle ridges or pronounced texture.

Size: not just about length and girth

Length and girth are the obvious metrics, but how they combine matters. A long, slender dildo may be easier to insert than a short, thick one. For custom options, you can often specify both dimensions. Start with a size that is slightly larger than what you currently use if you want to progress, but not so large that it causes discomfort.

Remember that silicone dildos have some give, so a thicker model in soft silicone might feel similar to a thinner one in firm silicone. Always check the insertable length, not just the total length.

Firmness: the overlooked variable

Firmness affects sensation, comfort, and ease of use. Soft silicone (Shore 00-30 or similar) bends easily and feels more realistic, but it can be floppy during insertion. Medium firmness (Shore 00-50) offers a good balance of flexibility and structure. Firm silicone (Shore A-20 or higher) holds its shape for targeted pressure but may feel unforgiving.

Custom dildo makers often offer multiple firmness options. If you are unsure, medium is a safe starting point. For textured or spiraled shapes, softer silicone can mute the ridges, while firmer silicone makes them more pronounced.

Decision rules for choosing your custom dildo

  • Rule 1: Match shape to stimulation goal: Choose a straight or slightly curved shape for G-spot or prostate targeting. Opt for a tapered or spiraled shape if you want to explore depth or enjoy a twisting sensation. For texture lovers, look for ripples or ridges.
  • Rule 2: Size up gradually: Measure your current comfortable girth and length, then add no more than 0.5 inches in circumference and 1 inch in length for your next toy. Custom dildos often allow you to specify exact dimensions. If you are between sizes, choose the smaller option first and size up later.
  • Rule 3: Let firmness match your texture preference: Soft silicone (00-30) is best for realistic feel and comfort; medium (00-50) for balanced use; firm (A-20+) for intense, targeted stimulation. Textured toys feel more pronounced in firm silicone. For a spiraled or ridged design, medium or firm silicone will make the texture more noticeable.
