When choosing a beginner butt plug, compare its dimensions, shape and base. Look for a gently tapered tip, clear width measurements and a substantial flared base that stays outside the body. Add lubricant that is compatible with the toy, then let comfort guide what you try.
Choose by width as well as length
Overall length is only part of the picture. The widest insertable point tells you more about the amount of stretch, while insertable length tells you how much of the toy is designed to go inside. Compare both.
“Small” is a label used by the manufacturer. It does not mean the same dimensions across different ranges, so read the measurements rather than shopping by that word alone. Compare listings in the same units so the dimensions are easy to understand.
A narrow tip that widens gradually gives you a different shape from a broad head with a sudden change in width. For a first purchase, we would prioritise clear sizing and a simple shape over texture, vibration or a large set.
The base is part of the design
Choose a toy designed for anal use, with a substantial flared base that cannot pass inside. The base needs to remain outside throughout use.
CNWL's NHS sexual health guide specifically advises a flared base for objects used for anal penetration. It also recommends slowing down or stopping at discomfort and seeking medical advice for pain or bleeding.[1]
Check the product photographs from the side as well as the front. You should be able to see the tip, the widest part, the narrower neck and the base. A decorative detail does not replace a substantial external base.
Think about firmness and finish
A flexible silicone plug and a firm metal plug will feel different even if their measurements look similar. Weight, flexibility and the shape of the base can all affect your preference.
For a first plug, we would generally compare a modestly sized, smooth, flexible option before buying a heavier or more complex design. That is a buying preference, not a guarantee of comfort for every body.
Check the exact material, not just the surface colour. Avoid making assumptions from phrases such as “silicone feel”, and read the care instructions before buying. A clear material specification helps you choose compatible lubricant and an appropriate cleaning method.
Butt plugs and anal beads have different shapes
A plug usually has a single insertable body, a narrower neck and a flared base. Anal beads have a sequence of rounded sections, so the width changes along the toy.
If you are comparing beads, check the diameter of the largest bead rather than only the smallest. Choose a purpose-made design with a reliable external stop and retrieval feature; inspect it before use and follow the manufacturer's directions. Avoid a toy with loose attachments or damaged joins.
Neither shape is a required next step after the other. Pick the one you are interested in, with dimensions and controls you can understand. You can also start with external touch and decide later whether you want a toy.
Choose the lubricant alongside the toy
The rectum does not provide enough natural lubrication for comfortable penetration. NHS guidance emphasises lubricant as part of reducing friction and discomfort.[1]
Use a lubricant that the toy manufacturer confirms is compatible. Water-based lubricant is a practical first option for many silicone toys. Reapply when needed rather than treating the first application as enough for the whole time.
If you use a condom on the toy, check compatibility with the condom as well. Our water-based versus silicone lube guide explains the differences to consider. The exact instructions on your toy and lubricant take priority over a general recommendation.
Make the first time unhurried
Clean the toy as instructed, check it for damage and give yourself time to see how it feels. You can stay with external contact before deciding whether you want to go further.
Apply lubricant and proceed gently. If you notice discomfort, slow down or stop; pain is a reason to stop and seek advice, not a target to work through. You can choose a smaller toy, return to external touch or finish for the day.
Keep the base outside and accessible. If you are with a partner, be clear about who is moving the toy and ask them to follow your pace. Specific feedback such as “Stay there for a moment” makes it easier to respond to what feels comfortable.
There is no schedule for trying a larger size. The smallest option in a set can be the only one you ever want.
Plan for cleaning before changing activities
Follow the manufacturer's cleaning instructions and let the toy dry before storing it. Our cleaning and care guide helps you check the method for different materials.
When changing between partners or body areas, clean the toy appropriately and use a fresh condom where suitable. NHS guidance recommends changing barriers between uses and partners. Keep toys used anally separate from vaginal use until they have been cleaned appropriately.[1]
If a toy becomes stuck, do not use tools or another object to retrieve it: seek urgent medical help. Persistent pain or bleeding also needs medical advice.
A few things people ask
What size should a beginner butt plug be?
There is no universal beginner measurement. Compare maximum width, insertable length and flexibility, and choose a modest size that feels manageable to you.
Should I buy a single plug or a set?
A single plug can be enough. A set gives you several dimensions to compare, but it does not mean you need to use each size.
Are metal plugs unsuitable for beginners?
Material alone does not decide suitability. Metal is firm and can be heavier, so consider size, weight, finish and the base together. We would usually compare a flexible option first if you are still learning what feels comfortable.
Can I leave a plug in overnight?
Avoid sleeping with a plug in. Follow the manufacturer's limits for use and remove it while you are awake and able to notice and respond to discomfort.
What if it hurts?
Stop. If pain persists or there is bleeding, seek medical advice. Adding a toy should feel like a choice you can pause or change at any point.
Read the dimensions, base design and care instructions before buying. Follow the manufacturer's directions when you use it.
