# Dildos: the four decisions that actually matter > A complete guide to choosing a dildo — girth before length, what the base decides, when material matters, and how the finish changes the feel. Canonical: https://weargoeasy.com/blog/dildos-the-four-decisions/ Updated: 2026-10-17 Publisher: WearGoEasy Market: Sultanate of Oman ## 1. Girth first, length second Length is printed on every listing because it is easy to measure. Girth is what decides comfort, and it is the number most listings leave out. A 3.5 cm shaft and a 4.6 cm shaft are genuinely different experiences at the same length. Our range runs from 3.5 cm to 6.5 cm; if you are unsure, start at 3.5–3.8 cm and go up on a second purchase. ## 2. The base decides how you use it **Suction base** — sticks to tile, glass and polished stone, so it works hands-free on a floor, a wall or the side of a bath. It does not stick to painted or textured walls. **Flat or rounded base** — sits in the hand or on a surface, and can be held in a harness. No suction. **No base at all** — only for use with a strap-on harness, where the harness holds it. This is a functional choice, not a cosmetic one. Decide how you want to use it before you look at the shape. ## 3. Material: silicone unless softness is the point Silicone is non-porous, cleans properly, and lasts years. Almost everything in this category should be silicone. The exception is realism — a softer material feels more lifelike, at the cost of a shorter life and more careful cleaning. That is a trade, not an upgrade. ## 4. Finish changes how it feels more than you expect A matte finish holds water-based lubricant better and feels warmer. A glossy finish looks more realistic but the lubricant slides off faster. If you have only used glossy ones and found them dry, try matte before assuming lubricant is the problem. ## Sizes across our range 13 cm at 3.8 cm — the starter size. 20 to 21 cm at 3.5 to 3.8 cm — long but slim. 21 cm at 4.6 cm — the realistic moulds, noticeably thicker. 37 cm — the double-ended one, flexible along its length rather than rigid. ## Frequently asked questions ### What size should a beginner choose? 3.5–3.8 cm of girth and 13–18 cm of length. Start narrower than you think you need. ### Does a suction base work on any wall? Only on smooth, non-porous surfaces — tile, glass, polished stone. Not on painted or textured walls. ### Silicone or realistic material? Silicone unless realism is the specific thing you want. It lasts longer and cleans better. ## Products mentioned - [Manual Dildo — 21 × 3.8 cm](https://weargoeasy.com/shop/manual-dildo-yb14/) - OMR 23.000 - Out of stock - [Motorised Realistic Dildo — 4.6 × 21 cm, 874 g](https://weargoeasy.com/shop/motorised-realistic-dildo/) - OMR 39.000 - Out of stock ## Related links - [Dildos](https://weargoeasy.com/shop/category/dildos/) - [How to make a suction cup stay put](https://weargoeasy.com/blog/how-to-use-a-suction-cup-dildo/) - [Dildo or vibrator](https://weargoeasy.com/blog/dildo-vs-vibrator/)
