Butt Plugs: Everything You Need to Know Before You Buy

Butt plugs are one of those things that are simultaneously very common and very under-explained. They're one of the bestselling categories in the entire sex toy industry, used by people across every demographic — and yet finding genuinely useful, non-awkward information about them can be surprisingly hard.

This is that guide. Let's get into it.

What Is a Butt Plug, Actually?

A butt plug is a toy designed specifically for anal insertion and retention. Unlike a dildo, which is typically used with in-and-out movement, a butt plug is designed to sit comfortably in place. The shape does all the work: tapered tip for easy insertion, a wider bulb in the middle, a narrowed neck that rests against the sphincter, and a flared base that stays outside the body entirely.

That flared base isn't a design flourish — it's a safety feature. It prevents the toy from being drawn into the rectum, which rectal muscles can do involuntarily. Every butt plug you consider should have one.

Why Do People Use Them?

A few reasons, and they're all valid:

Solo stimulation. The anal canal has a dense concentration of nerve endings, and the feeling of fullness that a plug provides is pleasurable in its own right for many people.

Prostate stimulation. For people with a prostate, a plug positioned correctly applies indirect pressure to the gland, which can significantly enhance arousal and orgasm. (More on direct prostate stimulation in our prostate massage guide.)

Enhanced sensation during other activities. Many people wear plugs during sex, masturbation, or even just around the house. The presence of the plug adds a layer of stimulation to everything else happening.

Preparation and training. Some people use progressively sized plugs to gradually and comfortably increase their capacity for anal play over time.

Sizing: Start Smaller Than You Think

This is the single most important practical point in this entire guide. Start smaller than you think you need to.

The anal sphincter is a muscle that needs time and relaxation to accommodate insertion comfortably. A toy that's too large too soon isn't just uncomfortable — it can cause micro-tears in sensitive tissue, which is both unpleasant and a health concern.

A good beginner plug is genuinely small — think the diameter of a finger, or slightly larger. Many sets come in graduated sizes specifically for this reason, letting you work up gradually over multiple sessions.

Materials

Silicone is the most popular material for butt plugs, and for good reason. It's soft, flexible, body-safe, non-porous, and easy to sterilize. Look for 100% body-safe silicone with no fillers.

Stainless steel plugs are firm, smooth, and completely sterilizable. They're also heavier, which some people find adds to the sensation of fullness. The weight stays constant — they don't compress or give — which makes the experience quite different from silicone.

Glass offers similar benefits to steel — firm, smooth, non-porous, temperature-play compatible. Our glass sex toys guide covers the specifics of borosilicate glass if you want the full picture.

Avoid: jelly rubber, PVC, and anything that smells strongly of chemicals. These materials often contain phthalates, are porous, and can't be properly cleaned. For anal use especially, this matters.

Vibrating vs. Non-Vibrating

Non-vibrating plugs are simpler and often a better starting point — there's less to think about, and you can focus on comfort and fit.

Vibrating plugs add a motor, either built into the plug or via a small bullet vibrator inserted into a hollow section. Many modern vibrating plugs are rechargeable and remote-controlled, which makes them practical for partnered play or hands-free use.

Neither is better than the other — it's just a different experience.

Lubricant: Use It Generously

No lube, no fun. The anus doesn't self-lubricate, so applying lubricant to both the toy and the body before insertion is essential. Use more than you think you need, and reapply if you're using the plug for an extended period.

Water-based lube works with all materials. Silicone-based lasts longer but degrades silicone toys — so if your plug is silicone, use water-based only.

Cleaning

Silicone: boil for 5–10 minutes, or top rack of the dishwasher, or soap and warm water. Stainless steel: boil, soak in diluted bleach solution, or dishwasher. Glass: same as stainless steel.

Clean thoroughly after every single use. For shared toys, use a fresh condom each time.

How Butt Plugs Fit Into the Bigger Picture

If you're building an understanding of anal play more broadly, our anal toys guide gives you the full landscape. And if you're interested in the specific type of stimulation that comes from targeting the prostate rather than general fullness, the prostate massage guide is your next read.

The Bottom Line

Butt plugs are simple in concept and deeply varied in practice. The fundamentals are always the same: flared base, body-safe material, plenty of lube, and a genuine willingness to start small and go slowly. Get those right and everything else follows.
