Anal depth play means going past the rectum. The rectum is roughly 12 to 15 cm (5 to 6 in) long, and at the top of it the gut turns a corner into the sigmoid colon. Most anal play never reaches that corner. Depth play is the practice of getting a toy around it, slowly, without hurting yourself. The corner is the whole subject. Everything below is about how to approach it.

What you are actually working with

Two rings and a bend. The outer ring is the one you know: it warms up, it relaxes, it stretches. A few centimetres behind it sits a second ring of muscle that you do not control directly. It opens on its own when the body decides things are fine. Past that is the rectum, which is fairly straight and fairly forgiving. Then the bend.

The bend is a turn, and the angle of it changes with how you are positioned, how full you are, and how relaxed the muscle around it is. A toy that goes in easily on your back can stop dead on your knees. That is not a size problem. That is geometry, and you solve it by moving.

Pain at the bend is a stop signal. The colon wall past that point is thinner than the rectum and gives much less pain feedback, which is exactly why forcing it is a bad idea: you can do damage before it hurts.

Usable length is the number that matters

Total length includes the base. Usable length is what can physically go in. On a 30 cm toy the difference is usually 3 or 4 cm; on a double-ended piece it can be 10 or more. Our product pages list both, per size, in cm and inches, and the size guide puts the whole range side by side.

For reference: the rectum alone holds something in the 12 to 15 cm range on most adults. A toy with 20 cm (7.9 in) of usable length is at the bend when it is hilted. A toy with 28 cm (11 in) is well into the sigmoid. Those are different activities, and the second one is what people mean when they say depth.

If you are reading this because you are comfortable with something around 15 cm and want more, the next toy is 20 cm. Skip the 30.

Shape does more than length

Three things make a toy easier to take deep, and none of them is "longer".

A thin tip. The first few centimetres do the negotiating with the second ring and with the bend. Stardust Shuttle starts at 4.5 cm (1.8 in) around on the S, about the width of a finger, and does not reach its full 16.3 cm (6.4 in) until well down the shaft, with 28.2 cm (11.1 in) usable in total. Winding Beaded Snake is built the same way: 5.4 cm (2.1 in) around at the tip on the XS, 22.1 cm (8.7 in) usable behind it. Both let the body open in steps instead of all at once.

Flex. A shaft that bends follows the turn instead of arguing with it. Softer silicone helps here, up to a point. Too soft and you lose the ability to steer, and steering is the entire skill.

A base you can hold. The long pieces in our range all end in something that cannot follow the shaft in: a flat disc, a suction cup, or the anchor shape on Winding, which exists for exactly this reason. For depth work your hand stays on that base the whole time, so the toy can come out as fast as it went in.

Knots, beads and wide heads are a separate thing. They give you a pop, one step your body opens for and closes behind, and that is a different kind of fun. It is not depth. A knot sitting at the bend is a bad combination, so keep those in the rectum where they belong. The plugs and the shorter pieces in the tapered range are the warm-up shelf.

How a session actually goes

Warm up with something you already take without thinking. A plug, a smaller dildo, fingers. Ten minutes, more lube than seems reasonable. The point is to get the outer ring bored.

Then the long piece, and here is where most people go wrong: they aim for the bend. Do not. Go in until you feel the toy meet something, and stop there. Breathe out. Shift your hips, change the angle, try a different position. The bend opens when the angle is right and the muscle is relaxed, and you will feel it as a slide rather than a push. If it does not come, it does not come today.

Reapply lube whenever movement gets less smooth. Water-based works with silicone toys and with condoms. Silicone lube lasts longer, but test it on a hidden spot of the toy first. Oil weakens latex condoms, so keep it away from those.

Numbing cream: no. The feedback you would be numbing is the only thing keeping you safe.

A tangent, since we get asked. Most of the depth footage online is filmed with people who have been at this for years, on toys with a lot of flex, at angles chosen for the camera. It is not a reference for a first session. It is barely a reference for a fiftieth.

Stop signals

Sharp pain. Burning. Anything that feels like a pinch or a fold that will not pass. Numbness. Blood beyond a spot. Dizziness. Cramping that keeps going after you have stopped. Any one of these: out, slowly, and done for the day.

Mild soreness the next morning is normal after any anal play. Pain that gets worse over 24 hours, fever, or trouble with bowel movements are not, and want a clinician. If a toy is stuck and you cannot get a hand on the base, that is an emergency department. Nothing from the kitchen drawer.

If the second ring will not relax no matter what you do, over weeks, that is worth a conversation with a pelvic floor physiotherapist. Muscles that stay clenched are a treatable thing, and none of the treatments involve pushing harder.

Cleaning

Platinum-cured silicone is non-porous. Warm water and an unscented soap, then dry completely before it goes back in the drawer. Do not move a toy from anal use to anything else without washing it, and use a fresh condom per person if a toy is shared.

Questions we get

How deep can you go?

Past the bend, the sigmoid colon runs roughly 35 to 40 cm and is not straight either. People do take 40 cm and more, after years, with a lot of flex in the toy. Most people settle somewhere between 18 and 28 cm usable, and there is nothing waiting past that except more turns.

How long does it take to get past the bend?

Some find it on the third session, some on the thirtieth, some never enjoy it and stop trying. It is a position and relaxation puzzle more than a training programme. Sessions where nothing happens still count.

Is a longer toy harder to use?

Not by itself. Tip width and flex matter more than the total. A 30 cm toy with a thin tip is easier to work with than a 20 cm one with a wide head.

Is a belly bulge safe?

A visible bulge means the toy has passed the bend and is pressing outward through the abdominal wall. Without pain it is not dangerous on its own, but it does mean you are in the sigmoid, so slow down and keep your hand on the base.
