What is a butt plug?

A butt plug is a tapered anal toy designed to be inserted and worn comfortably, with a flared base to keep it secure. Unlike an anal dildo, a butt plug is shaped to stay in place rather than to be thrust in and out. Butt plugs can create a feeling of fullness, and people of any gender can use them.

Most butt plugs are shaped with:

a tapered tip for easier insertion
a fuller middle for a satisfying feeling of fullness
a narrow neck to help keep the toy in place
a flared base for safety

That shape is what makes a butt plug different from other anal toys.

Toy	Best for	Key difference
Butt plug	Wearable fullness and targeted stimulation	Designed to stay in place with a narrow neck and flared base
Anal beads	Gradual sensation and progression	Made up of separate beads rather than one tapered body
Anal dildo	Length and thrusting	Usually longer and not primarily designed for wearing

What does a butt plug do?

An anal plug creates a feeling of fullness and can add extra stimulation during solo or partnered play. Some people use butt plugs as a way to explore anal play gently, while others use them as part of foreplay or to prepare for anal sex.

For beginners

For many beginners, a butt plug is one of the easiest ways to explore anal play. A small, slim silicone plug gives you a gentler starting point and lets you go at your own pace.

For men and prostate-focused play

Some butt plugs for men are shaped specifically as a prostate massager to provide more targeted internal pressure. Hitting the P-spot directly can turn a simple feeling of fullness into a powerful, full-body orgasm. If that is what you are looking for, start with a slim, body-safe curved design that feels comfortable rather than intense.

For women and added fullness

Many women enjoy the added sense of fullness an anal sex toy can bring during solo or partnered play. Smooth, tapered styles are usually the easiest place to start.

For couples

Butt plugs can also work beautifully during foreplay or partnered play, especially if you choose a vibrating or remote-controlled style. The key is always comfort, communication and plenty of lubricant.

How to choose the right butt plug

The best butt plug is the one that feels right for your body, your confidence level and the kind of sensation you want. The easiest way to narrow it down is to choose by size, material and style.

Choose by size

When it comes to butt plugs, width matters more than total length. If you are deciding between small, medium and large, the two most useful measurements are:

Diameter – the width across the widest part of the plug
Circumference or girth – the distance around the widest part

These measurements tell you how full the anal toy is likely to feel. In simple terms, the wider the bulb, the more noticeable the sensation. Length matters too, but it is usually the width that determines whether a sex toy feels beginner-friendly or more advanced.

At Secrets Shop UK, the simplest beginner rule is this: start smaller than you think you need. A slim, tapered shape is usually the most comfortable place to begin.

Experience level	Diameter at widest point	Circumference / girth	Typical feel	Best shape	What to avoid
Small / beginner	Up to 1.1 in/ 2.8 cm	Up to 3.5 in / 8.9 cm	Light fullness and the easiest starting point	Slim, tapered silicone plug	Heavy metal, aggressive texture or oversized bulbs
Medium	1.2–1.4 in / 3.0–3.6 cm	3.75–4.5 in / 9.5–11.4 cm	A fuller, more noticeable fit	Smooth teardrop or slightly weighted plug	Jumping straight here if you are brand new
Large / advanced	1.5 in+ / 3.8 cm+	4.75 in+ / 12.1 cm+	Strong fullness, better for experienced users	Larger bulb, weighted, inflatable or advanced styles	Going too large too quickly

Size note: butt plug sizing is not perfectly standard across every brand, so use the diameter and circumference at the widest point as your best guide to fullness.

A simple rule to remember:

Small butt plugs are usually up to 1.1 inches wide
Medium butt plugs are usually around 1.2 to 1.4 inches wide
Large butt plugs usually start at around 1.5 inches and above

If you are buying your first anal sex toy, go by width first, not length. A longer toy can still feel beginner-friendly if it is slim, while a short plug with a wider bulb can feel much more advanced.

Choose by material

For insertable toys, non-porous materials such as 100% silicone, stainless steel and glass are usually the safest starting point. They are easier to clean properly than porous materials such as jelly, PVC, vinyl, TPR or TPE.

Silicone butt plugs

A silicone butt plug is usually the best place to start. Silicone feels softer, more flexible and more forgiving, which makes it ideal for beginners and for comfortable wear.

Glass butt plugs

A glass butt anal toy feels smooth, sleek, and firm. Because glass retains temperature, it is perfect for temperature play - simply warm it in water or cool it in the fridge for a highly stimulating, defined sensation.

Metal anal plugs

A metal butt plug offers weight, pressure and a very smooth surface. Metal styles appeal to more experienced users or anyone who prefers a firmer feel. Like glass, metal is fantastic for temperature play.

Jewelled butt plugs

A jewel butt plug combines practical pleasure with decorative styling. It is a lovely choice if you want something glamorous, giftable or visually playful.

Inflatable butt plugs

An inflatable anal toy gives you more control over fullness because it starts smaller and expands gradually. It is usually better suited to shoppers who already know what feels comfortable for them.

Best butt plug by goal

Best butt plug for beginners: A small silicone butt plug or a graduated set is usually the best choice. Look for a slim tapered tip, flexible body and secure flared base.
Best butt plug for prostate play: A curved anal sex toy or slim vibrating design can work beautifully to hit the P-spot.
Best butt plug for wearing during sex: Choose a smooth design with a comfortable neck and a base that sits neatly in place. Silicone and metal are both popular here.
Best butt plug for training up sizes: A graduated set is ideal if you want to progress slowly. It takes the guesswork out of sizing and helps you build confidence step by step.
Best butt plug for aesthetics or tail play: If style matters as much as sensation, a jewelled or tail design is the obvious choice. These styles are popular for gifting, dressing up and adding something more decorative to your toy collection.

Butt Plug Usage and Safety

Butt plugs are safe when used correctly, but safe anal play depends on three basics: a proper flared base, plenty of lubricant, and a butt plug that is designed specifically for anal use. The anus does not self-lubricate, and toys without a proper base can be pulled inward and become difficult to remove.

Essential safety features

The most important rule is simple: always choose an anal plug with a flared base. That wide base helps keep the toy secure and makes removal easier. Never use any object that is not specifically designed for anal play, as anything without a proper base can slip too far inside and may require medical removal.

Materials and lubrication

Choose a non-porous body safe material where possible, such as 100% silicone, stainless steel or glass. These are easier to clean thoroughly. Always use plenty of lubricant.

A water-based lube is the safest all-round choice and the best default for silicone toys. If you prefer a thicker, longer-lasting feel, silicone-based lube can work with some glass or metal toys, but it should not be used with silicone plugs.

Tips for beginners

If you are new to butt plugs, start with a small, tapered beginner plug or a training set. Apply lubricant to both the toy and your body, relax, and insert the plug slowly rather than forcing it. Mild pressure can be normal at first, but sharp pain is not. If anything feels painful, remove the toy and stop.

It is best to begin with short, comfort-led sessions and build up gradually as your body gets used to the sensation. Lying on your side with your knees pulled to your chest or resting on all fours are the most comfortable positions for beginners.

When to take extra care

If you have haemorrhoids, anal fissures or prostate-related conditions, it is sensible to check with a clinician before using a plug, as anal play may aggravate symptoms.

How to clean and store a butt plug

Proper cleaning matters just as much as choosing the right size. Clean your anal toy before and after every use with warm water and a mild, unscented soap, then follow any brand-specific care instructions for the material and motor.

Before use

Wash the toy, rinse it well and check that the surface is smooth and undamaged. If it vibrates, make sure it is charged and that you know whether it is waterproof or splashproof.

After use

Clean it thoroughly as soon as possible after use. Dry it completely before putting it away.

Storage

Store your butt plug in a clean pouch, storage bag or separate compartment. So it stays dry, dust-free and protected from rubbing against other materials.

Sharing and cross-contamination

Do not move a toy or fingers from anal to vaginal use without washing them first or changing the condom on the toy. That helps reduce the risk of transferring bacteria. If a toy is being shared between partners, clean it thoroughly and use a fresh condom between users.

Common butt plug mistakes to avoid

A few simple mistakes can make the experience less comfortable than it needs to be. The good news is they are easy to avoid.

choosing a size that is too large too soon
focusing on length instead of width
buying a plug without a proper flared base
not using enough lubricant
using silicone lube with a silicone anal plug
rushing insertion before your body feels relaxed
not checking the material before you buy
skipping cleaning and safe storage
moving from anal to vaginal use without washing the toy or changing the condom first

FAQs

What size butt plug is best for beginners?

A small silicone plug with a slim tapered tip, narrow neck and flared base is usually best for beginners.

What do diameter and circumference mean on a butt plug?

Diameter is the width across the widest part of the plug. Circumference or girth is the distance around the widest part. Both help you understand how full the plug is likely to feel, but diameter is often the easiest measurement to picture.

Are butt plugs safe?

Yes, anal plugs can be safe when you choose a body-safe toy with a flared base, use plenty of lubricant and stop if anything feels painful or uncomfortable.

Can men use butt plugs?

Yes. Many shoppers specifically look for anal plugs for men or male anal plugs, especially as a prostate massager. Hitting the P-spot requires choosing a size and curved shape that feels comfortable.

Can women use butt plugs?

Yes. Many women enjoy anal plugs for added fullness during solo or partnered play. A small, smooth, tapered plug is usually the easiest place to start.

What lube should I use with a butt plug?

A good water-based lubricant is the safest starting point for most people and is mandatory with silicone toys. If you are using a glass or metal toy, you can explore silicone or hybrid lubes for a longer-lasting glide.

How long can you wear a butt plug?

Start with shorter, comfort-led sessions and listen to your body. If you notice pain, irritation, numbness or pressure, remove it straight away. Medical guidance does not set a single fixed wear-time rule, so comfort and common sense matter most.

Can I switch between anal and vaginal play?

Not without cleaning first. Never move a toy or fingers directly from the anus to the vagina without washing them or changing the condom first.

What’s the difference between a butt plug and anal beads?

A butt plug is designed to stay in place and create a feeling of fullness. Anal beads are designed for a different type of sensation and are not the same as a standard plug.
