Butt Plug Sizes: How to Choose the Right Size, Material and Care
Share
If you're thinking about trying a butt plug, the most useful thing you can do is read up before you buy. Butt plug sizes vary a lot, and the best starting point is usually smaller than people expect. This guide narrows the decision down to four things: size, material, base and care.
Start small, then decide
For a first plug, the most sensible rule is to start with a small size. A small size lets you get to know the sensations without forcing anything, and you can always move up later. Choosing a large size "so you don't have to buy another" usually works out worse than the opposite.
Look at two measurements: the insertable length and the maximum width. The total length includes the base, which is not inserted.
Non-porous, body-safe, easy to clean
Look for a non-porous material that is easy to clean. Good-quality silicone meets both requirements, which matters especially for a toy used anally. On their product pages, SILEXD plugs are described as follows:
- Premium silicone. A soft outer layer over a dual-density SILEXPAN® core, with a firmer inside.
- Body-safe and non-porous. The surface doesn't hold on to residue, so cleaning is simple.
- Phthalate-free. Listed as certified phthalate-free on the product pages.
The base is non-negotiable
For anal use, a toy needs a base that is wider than the rest of its body, so it cannot slide in completely. It's a basic safety rule, and worth checking on any plug before you buy it.
One rule has no exceptions: if it hurts, stop. If you feel sharp pain or notice bleeding, stop using the toy and speak to a healthcare professional.

How to use a butt plug, step by step
Relaxation matters more than any technique, so pick a calm moment with no rush.
- Clean the toy before use with warm water and a mild soap.
- Use plenty of lubricant. The body doesn't lubricate itself here, so be generous and reapply when needed.
- Start on the outside: a gentle massage of the area helps everything move at a comfortable pace.
- Insert the plug slowly, with the tip well lubricated and without forcing it. If you feel resistance or discomfort, stop, breathe and start again more slowly, or leave it for another day.
- Remove it just as slowly.
- Clean it as soon as you finish.
Which one to use
For SILEXD plugs, the recommendation in our lubricant compatibility guide is clear:
- Water-based. The safest and most versatile option, compatible with SILEXPAN® and with most condoms.
- Aloe vera-based. A good alternative if you prefer a more natural formula.
- Avoid. Silicone-based lubricants, which can damage the surface with repeated use, and oil-based ones, which leave residue and aren't compatible with latex condoms.
Cleaning and storing your plug
Cleaning is simple if you always do it the same way. Our cleaning and care guide covers it in more detail:
- Rinse with warm water straight after use.
- Wash with a mild, unscented soap that contains no alcohol. A non-porous surface releases dirt easily, so there's no need to scrub hard.
- Rinse thoroughly and dry completely.
- Store in a fabric bag, away from sunlight and heat, without touching other silicone toys.
If you share the toy with another person, clean it between uses and use a condom.
Frequently asked questions
What size butt plug should a beginner start with?
The smallest one in the range. You can move up in size later if you want to, but starting small lets you get to know the sensations without rushing.
How long can you wear a butt plug?
There's no universal time we can recommend. Start with short sessions, listen to your body and remove the plug if you feel discomfort. If you have any doubts, speak to a healthcare professional.
Do you need lubricant?
Yes, always, and plenty of it. The area doesn't lubricate on its own. With SILEXD plugs, choose a water-based or aloe vera-based formula.
Can you use a butt plug with a condom?
Yes, and it's good practice if you share the toy with another person. Check that the lubricant is compatible with the condom.
How can you tell a butt plug is safe?
Check that the material is non-porous, that the plug has a wide base and that the manufacturer says what it's made of. Above all, always use lubricant and stop if you feel pain.
Start small, go slow
Choosing a butt plug comes down to four decisions: a small size to begin with, a non-porous material, a wide base and a water-based lubricant. With those and a little patience, you have the basics covered.
