Advanced anal toys: what changes after the beginner set
What actually changes when you move past a starter plug: diameter, firmness, weight and material. An honest UK guide to advanced anal toys and silicone anal toy
Published 4 September 2026 · 11 min read · Reviewed by the UK SEX TOYS product team

Most anal guidance is written for the first week. Start small, use more lubricant than you think, stop if it hurts. That advice is correct, and we have written our own version of it in Anal play, done carefully. It also runs out fast.
This guide starts where that one stops. You already own something that works. You want to know what the next purchase should be, and whether "advanced" means anything more useful than "bigger".
It does. Size is the least interesting axis of the four.
"Advanced" is four variables, not one
Every anal toy differs along four measurable lines. Beginners change one at a time and are told to change diameter. Experienced users usually get more out of the other three.
Diameter is the widest point of the insertable section. It is the number people fixate on and the one that causes injury when rushed.
Insertable length is how much of the toy is designed to go in. Across our butt plugs this runs from 15mm to 381mm, and those two ends of the range are entirely different products for entirely different people.
Firmness is how much the material yields under pressure. Two plugs with identical dimensions can feel nothing alike. A soft silicone plug at 40mm diameter is often easier than a rigid glass one at 32mm, because soft silicone compresses on entry and re-expands once past the tightest point.
Motion is whether the toy does anything: vibration, rotation, weight that shifts as you move, beads that travel. A static plug and a vibrating one at the same dimensions are not the same experience or the same wear time.
The practical version: if your current toy is comfortable, do not automatically buy a wider one. Buy the same width in a firmer material, or the same width with weight, or the same width with a curve. You will learn more about what you actually like, and you will not lose three weeks to an over-ambitious purchase that sits in a drawer.
The base rule does not relax with experience
Every insertable product in our anal department has a flared base or a retrieval loop. All 108 of them. That is a safety requirement, not a house style, and it is the one rule that gets stricter as toys get more advanced rather than looser.
The anatomy here is a one-way system. The rectum draws objects inward through normal muscular action, and there is no natural stopping point the way there is elsewhere in the body. A toy without a base that is wider than the widest insertable point can migrate past the point of retrieval. The resulting procedure is a hospital one, and A&E departments perform it regularly enough that the statistics are unremarkable to the staff and mortifying to the patient.
Three things people get wrong once they are past the beginner stage:
A narrow neck is not a base. The base must be meaningfully wider than the shaft in at least one dimension, and it must be rigid enough not to fold. A flexible disc that compresses to the width of the shaft under muscle pressure is decorative.
T-bars beat circles for wear. For anything you plan to wear while sitting or walking, a flared base shaped as a bar or teardrop sits between the buttocks more comfortably than a flat circle, which is why most of our larger plugs use one.
Retrieval loops are a different mechanism, not a weaker one. Anal beads use a loop rather than a flare because the product is designed to be withdrawn in sequence. The loop must be attached to a cord you can hold under tension without it stretching to nothing. Check that before use, not during.
Glass and metal deserve a specific note. A borosilicate glass plug is safe and strong under normal use, but it is unforgiving of impact. Do not use one that has been chipped or dropped onto a hard floor, and do not test one for cracks by squeezing it.
Diameter: the numbers that actually matter
The useful working range for most people sits between roughly 25mm and 45mm at the widest point. Below that is starter territory. Above it, progress slows dramatically and the time investment rises out of proportion to the return for most users.
Move in steps of around 5mm, and give each step at least two or three sessions across a fortnight before deciding it is comfortable. The tissue involved does adapt, but it adapts on a timescale of weeks. A session where something felt fine at the time and sore the next day was too much, regardless of how it felt at the time.
The taper matters as much as the maximum. A plug that reaches 40mm gradually over 90mm of length is a genuinely different proposition from one that reaches 40mm in 25mm of length. Steep tapers feel dramatic on entry and are harder to control. Gradual tapers give you a decision point at every stage. When you are sizing up, buy the gradual one.
Firmness, and why advanced users often go softer
Silicone is specified by shore hardness. Most manufacturers do not print the number, which is unhelpful, so you are usually judging from photographs and descriptions. The honest signals: a toy that visibly bends in a product image is soft, a toy photographed holding a rigid straight line is firm, and anything described as "ultra-soft" is at the yielding end.
Firm materials transmit sensation precisely and hold their shape against muscle pressure, which is what you want for prostate work. Soft materials compress on entry, which is what you want when you are increasing diameter. These are different goals, and a collection of two or three toys handles them better than one compromise toy.
This is the single most common mistake we see in the step up from beginner to intermediate: buying a larger version of a firm toy, when a larger version of a soft toy would have been the achievable next step and a firmer version of the same size would have been the more interesting one.
Material as a sensation, not just a safety category
Every material we stock is non-porous and body-safe — that part is covered in Materials, and what body-safe actually means. What changes at this level is that material becomes something you choose for how it feels rather than something you check for safety.
Body-safe silicone is the default and accounts for 58 of the products in the anal department. It warms to body temperature, grips slightly, and forgives imprecision. It is also the only material here with a lubricant restriction: keep silicone-based lubricant away from it.
Borosilicate glass is rigid, slick, and holds temperature. Run it under warm water for a minute before use, or cool it, and you have a genuinely different sensation from the same shape in silicone. It takes any lubricant. It is also heavier than it looks, which contributes to the sensation of fullness at a smaller diameter.
Anodised aluminium — the Basalt Bloom is our example — is the weight option. Metal plugs feel substantially larger than their measurements because mass registers as pressure. This is why a 30mm aluminium plug can feel more present than a 38mm silicone one, and why metal is worth trying before you assume you need to size up.
Stainless steel behaves like aluminium with more weight again, and holds temperature longer.
The temperature point is worth spelling out because it is genuinely one of the better-value ways to make an existing size feel new. Warm water only. Never a microwave, never a freezer, never boiling water immediately before use. Body-adjacent temperature, tested against the inside of your wrist, is the whole technique.
Prostate massagers are a different axis entirely
Fifteen products, and insertable lengths start at 35mm. That number surprises people who assume prostate work requires length.
It does not. The prostate sits roughly 50–70mm inside, towards the front of the body. What matters is the angle of the curve and the firmness of the material, not how far the toy reaches. A short, firm, well-curved massager will do more than a long soft one, and the long soft one will mostly feel like a long soft one.
If you are moving from plugs to prostate massagers, treat it as a new category rather than a size increase. Start at the shorter, firmer end. Halcyon Taper and Ivory Anchor sit at the accessible end of the range; Apex and Vertex are considerably more specialised. Expect the sensation to be unfamiliar rather than simply "more" — many people describe the first successful session as diffuse and slow-building rather than sharp, and several sessions are often needed before it registers as pleasurable at all.
Wear time, weight, and the things nobody mentions
Plugs designed for wearing are a genuine sub-category, and the constraints are practical.
Weight works against you over time. A metal plug that feels excellent for twenty minutes is a different object at two hours. Start at fifteen to twenty minutes and build.
Lubricant does not last as long as you expect. Water-based lubricant dries or absorbs; if you are wearing something for an extended period, either choose a thicker formulation or accept that removal may need re-lubrication rather than force. Our anal lubricants are formulated thicker than the general range specifically for this.
Numbness is a stop signal, not a milestone. Reduced sensation means pressure is affecting circulation or nerve response. Remove and take a break.
And do not sleep in one. Nothing about the situation improves while you are unconscious.
Cleaning, at this level
The routine from Cleaning and storage still applies, with two additions.
Anything used anally is cleaned before it goes anywhere else, without exception and without shortcuts. Bacteria that are entirely normal in one part of the body cause infections in another. If a toy is shared between partners or between body areas, a condom over the toy, changed between uses, is the practical solution.
Textured toys, beads and anything with seams or joins need attention in the crevices rather than a wipe over the surface. Silicone that can be boiled should be boiled periodically. Anything with a motor or a battery cannot be boiled, and a dedicated cleanser is the correct answer for those.
Douching: the honest position
We stock eighteen anal douches, so it would be strange to pretend the question does not come up.
It is optional. Plenty of people never do it. The lower rectum is generally empty, and a normal shower with clean hands is sufficient preparation for most play.
If you do douche: use plain warm water, use less pressure and less volume than seems intuitive, and do it well in advance rather than immediately before. Over-douching strips the mucosal lining, which increases irritation and, over time, makes tissue more fragile rather than less. Frequent, high-volume douching is the practice most likely to cause the problems people are douching to avoid.
Anything involving persistent bleeding, pain that outlasts the session, or a change in bowel habit is a conversation with a GP rather than a product problem. That is not a disclaimer — it is the correct next step, and it is a very ordinary appointment for a clinician.
A progression plan that works
If you want a concrete sequence rather than principles:
- Stay at your current diameter and change material. Buy glass or aluminium in a size you already handle comfortably. Learn what weight and temperature do.
- Add one size step in soft silicone. Roughly 5mm wider, gradual taper. Two weeks before judging.
- Add curve, not size. A prostate massager or a curved plug at a familiar diameter.
- Add motion. Vibration at a familiar size and shape, so only one variable is new.
- Only then, size up again.
Most people find they stop wanting step five somewhere around stage three, which is the actual point of laying it out this way.

Frequently asked
- What counts as an advanced anal toy?
- Not simply a large one. Advanced usually means a combination of firmer material, added weight, a pronounced curve, or motion — at a diameter the user already handles comfortably. Diameter alone is the crudest measure of progression.
- Are silicone anal toys better than glass or metal?
- They are different rather than better. Silicone is soft, warm and forgiving, which suits increasing size. Glass and metal are rigid and hold temperature, which suits precision and sensation variety. Silicone is the only one of the three with a lubricant restriction.
- Why does every anal toy need a flared base?
- Because the rectum draws objects inward and has no natural stopping point. A base wider than the widest insertable section is what allows retrieval. Every insertable product in our anal department has a flared base or a retrieval loop for this reason.
- How quickly can I size up?
- In steps of roughly 5mm, with two to three sessions across a fortnight at each step. Soreness the following day means the last step was too large, even if it felt manageable at the time.
- Do I need to douche before anal play?
- No. Many people never do. If you choose to, use plain warm water, low volume and low pressure, well before rather than immediately before, and infrequently — over-douching irritates the tissue it is meant to protect.
