Butt plugs are one of the most popular and consistently purchased sex toys in the world — and yet they remain one of the most misunderstood. Whether you're completely new to the idea or simply looking to understand more before making your first purchase, this guide covers everything you need to know: what a butt plug is, how it works, what materials to look for, and how to use one safely and comfortably.
If you want broader context on anal play before diving in, our blog Best Anal Toys for Beginners: Safe, Comfortable & Fun Options covers the full category — butt plugs, beads, vibrators, and more — in one place.
What Is a Butt Plug?
A butt plug is a toy designed for anal insertion. The shape typically starts tapered at the tip for ease of entry, widens into a bulbous body — sometimes with ridges, nubs, or nodules — before narrowing to a neck that sits comfortably inside the sphincter once inserted. Plugs can be straight or slightly curved, and are available in materials ranging from soft and flexible to completely rigid.
The single most important safety feature of any butt plug is a flared base or handle. Unlike the vagina, the anal canal has no natural stopping point — which means any toy without a flared base can slip fully inside and become very difficult to remove. The base must be significantly wider than the neck of the plug. This is non-negotiable.
Some styles feature gems embedded in the base for aesthetic appeal, and some come with furry animal tails or other accessories for role-play and kink purposes. Browse our full butt plugs collection for options at every size, material, and style.
Choosing the Right Size
Pay careful attention to both the length and width of any butt plug before purchasing. The sphincter can be quite tight — particularly for first-time users — and starting too large is the most common beginner mistake. Start with the smallest size available. You can always work your way up gradually as your body becomes more comfortable, and the experience will be significantly better for the patience.
Trainer kits — sets containing three or more progressively sized plugs — are an excellent investment for beginners because they allow you to progress at your own pace without needing to buy multiple individual toys. Look for these in our butt plugs collection.
What Materials Are Best?
The best butt plugs are made from non-porous materials — meaning they can be fully cleaned and sterilized without bacteria harbouring in microscopic pores beneath the surface. Here's a breakdown of the most common options:
- Stainless steel — rigid, weighty, completely non-porous, and excellent for temperature play. One of the easiest materials to sterilize. A premium choice for experienced users.
- Borosilicate glass — smooth, non-porous, and also great for temperature play. Inspect carefully before each use and retire immediately if any chips or cracks appear.
- Silicone — ranges from soft and flexible to nearly rigid depending on the formulation. Body-safe, non-porous, and available in the widest variety of shapes and sizes. The most beginner-friendly material.
- ABS plastic — hard, smooth, non-porous, and lightweight. A solid mid-range option.
- Ceramic and treated wood — non-porous and beautiful, though less commonly found. Treat with the same care as glass.
Always avoid porous materials like jelly, rubber, TPR, or PVC for anal toys — these cannot be fully sterilized and harbour bacteria inside the material itself. Our blog Top 5 Myths About Sex Toys Debunked covers material safety in detail and is well worth a read before you shop.
Why Do People Use Butt Plugs?
The most common reason is the sensation of fullness — a feeling of internal pressure that many people find deeply pleasurable on its own, and that amplifies other forms of stimulation significantly when combined. People use butt plugs in a wide variety of ways:
- During partnered sex — worn by one or both partners to create a sensation of double penetration and enhance overall pleasure.
- During solo play — combined with a vibrator, dildo, or other toy for layered stimulation.
- For prostate stimulation — a curved plug targeting the prostate can produce incredibly intense orgasms for people with prostates. Our blog Prostate Stimulation for Health and Pleasure covers this in full.
- For anal training — worn for extended periods to gradually increase comfort with anal play and prepare for larger toys or penetration.
- As part of kink or BDSM play — as an element of power exchange, submission, or as an accessory in role-play scenarios.
Some butt plugs vibrate — either with a built-in motor or via remote control — adding an additional layer of stimulation. Some even deliver mild electrical sensations for more advanced users.
The Essential Role of Lube
The anus cannot self-lubricate — which means lube is not optional. It is essential for every single use, without exception. Inserting any anal toy without adequate lubrication risks discomfort and potential injury to delicate tissue. Use a generous amount and reapply as needed.
Water-based lube is compatible with all toy materials and is the safest universal choice. Silicone-based lube lasts longer but should not be used with silicone toys — do a spot test first by applying a small amount to the base of the toy and rubbing vigorously for five minutes. If the texture becomes tacky, the materials are incompatible and you should stick to water-based.
