Advanced Fisting: Deep, Double, Rosebud & Subspace

You’ve got the basics down. The hand goes in without much effort, warming up is routine, the trust with your partner is there. Now you want to go deeper, literally and figuratively. This guide shows you what really happens in advanced fisting: anatomically, technically and mentally. No myths, no exaggeration, but solid knowledge from workshops, medical literature and the experience of a community that has lived this for decades.

Important first: this article is aimed at people with fisting experience. If you’re just starting out, better begin with our fisting for beginners guide. Advanced techniques assume your body is used to simple fisting, otherwise you risk real injury.

1.1 What does “advanced” mean in fisting?

There’s no official definition. But if you tick at least three of the following, you’ve arrived in the territory this is about:

• You take a whole hand up to the wrist without significant warm-up beyond 30 minutes
• You have experience with various positions and know which works for your body
• You fist regularly, at least once a month over the course of a year
• You know the basics of hygiene, lube, safer fisting and aftercare
• You want to go deeper (deep fisting), more (double fisting) or into new territory (rosebud, subspace)

Advanced doesn’t mean “more extreme”. It means “more aware”. Anyone fisting at an advanced level knows exactly where their own limits lie, knows their body’s signals and respects them. That’s the difference between experienced and reckless, or, put briefly, between a pro and an anecdote in A&E.

1.2 Understanding the anatomy: where does the hand go?

In simple fisting your hand stays in the rectum, the last section of the large bowel before the anus, about 12–15 cm long. The rectum is a relatively straight tube with stretchy walls that tolerates a lot.

In advanced fisting it gets more interesting. The following structures come into play:

What most beginners don’t realise: the bowel doesn’t continue straight. At the level of the sigmoid it makes a distinct S-bend. This curve is the main reason deep fisting takes practice: the hand has to be able to take the bend without overstretching or injuring the bowel. Anyone trying to go through by brute force literally hits an anatomical wall.

1.3 The sigmoid: the second entrance

At about 10–15 cm depth your hand meets the puborectal sling, a muscle ring at the transition from rectum to sigmoid. Many bottoms describe it as a “second entrance”. The muscle holds the bowel at an angle and regulates the flow of stool.

When your hand reaches this point, three things happen at once:

1. The bottom feels marked pressure and often the urge to defecate. The reflex is normal but passes within a few seconds in trained bottoms.
2. You feel resistance, not the firm stop of a sphincter, but more an elastic “keep going, but slowly”.
3. The angle changes. From here you follow the curve of the bowel, no longer the straight line from the anus.

Reaching the sigmoid doesn’t automatically mean you’re deep fisting. It means you’re at the threshold. Anyone who pushes through the puborectal sling without the bottom being with them risks tears at the transition, one of the most common injuries in advanced fisting.

2.1 Deep fisting: step-by-step guide

Deep fisting means the hand advances beyond the rectum into the sigmoid. Some bottoms go up to the elbow (“elbow deep”), which is the upper limit of what’s anatomically safely possible.

Prerequisites that must be met without exception:

• At least 6–12 months of regular fisting experience
• Thorough bowel cleansing the day before and on the day itself
• At least 60 minutes of warm-up before the first attempt at depth
• An experienced top who knows exactly when to stop
• Full concentration on both sides. Deep fisting is not a “quick one in between”

How a typical deep session runs:

1. Classic warm-up (30–45 minutes): until the hand is in up to the wrist without trouble and the bottom is relaxed.
2. Find the puborectal sling (5–10 minutes): hand with extended but slightly curved fingers, slowly deeper. You feel the transition. The bottom breathes calmly and says when they feel pressure.
3. Wait, don’t push: at the sling, no pressure. The hand stays. The bottom breathes. After 30–60 seconds the muscle often opens of its own accord; you feel it as a sudden “letting go”.
4. Follow the angle: the hand follows the curve to the left (anatomically), not straight on towards the spine. That’s the most common mistake.
5. Go deep with care: a pause per centimetre. Going 10 cm deeper in 30 seconds is too fast.
6. Hold, don’t move: at maximum depth, no thrusting or pumping. Light turns of the wrist are enough. Thrusts in the sigmoid can cause tears.
7. Come out as slowly as you went in: on the way out, the same angle back, then straight. Never abruptly.

A regular at our workshops in Berlin, let’s call him David, puts it like this: “The first time deep is like the first time taking a hand. The whole time you think something bad is about to happen, because it feels so different from everything before. And then something opens, and you understand why people talk about it.”

2.2 Positions for deep fisting

Not every position is suitable. For deep fisting there are three that are regularly recommended:

All fours is often recommended but is suboptimal for deep fisting: the angle to the sigmoid is less favourable and the bottom can relax less. If you like all fours, use it for the warm-up phase and switch to one of the three positions above for the deep part. It looks impressive in videos but works in practice about as well as stilettos on a hike, nice to look at, impractical on the terrain.

2.3 Common mistakes in deep fisting

Ignoring the angle. The sigmoid goes to the left (from the bottom’s perspective). Pushing straight on presses against the bowel wall instead of through the curve. Risk: tears at the sigmoid transition.

Wanting it too fast. Deep fisting isn’t something you manage in the first session. Anyone wanting to advance past the sling for the first time should plan at least three separate sessions just for the approach.

Thrusting movements at depth. In the rectum small thrusts are okay. In the sigmoid they’re not. The bowel wall there is thinner and more mobile; thrusts can cause wall irritation or, in extreme cases, perforations.

Ignoring the urge to defecate. When the bottom reports the urge, that’s a physical signal. In trained bottoms it passes after a short pause. If not: break, maybe the toilet, then start again.

Starting without a pre-toilet. Stool residue sits in the sigmoid that isn’t yet noticeable in the rectum. Anyone going deep rinses twice: once an hour before, once right before the session. More in our hygiene guide.

Underestimating dehydration. Deep sessions stretch over hours. Both people lose fluid, through sweating, through breathing, through the effort. Keep water and electrolytes within reach. A deep session is closer to a hike than to sex as far as fluid needs go; carrying on just short of collapse means you’ve missed the point.

3.1 Double fisting: two hands, one bottom

Double fisting (also DPP, double penetration with punch) means two hands are in the anus or vagina at the same time. It isn’t necessarily “deeper” than single fisting, it’s wider. The anus has to stretch to about double the normal fist width.

Realistically, this is practised by a minority of fisting bottoms. Anyone wanting to try it should bring the following prerequisites:

• At least 2–3 years of fisting experience with large toys
• Experience taking a forearm (forearm fisting)
• Ideally existing sphincter stretch from plug training
• Two tops who can coordinate well, or one top with two hands, which is usually considerably harder

3.2 Double fisting step by step

1. Single fisting to maximum stretch: one hand is in, the anus is well opened. That’s the starting point.
2. Introduce the second hand in parallel: both hands in duck’s-beak position, thumbs facing each other, parallel side by side. The first top holds their hand still, the second top slides in slowly.
3. The second fist overlaps with the first: both thumbs lie against each other, the hands partly cross. Never press both hands in as complete fists.
4. Hold position: minimise movement. Double fisting is more a “fullness experience” than a “movement experience”.
5. Out one after the other: one hand out first, then the second. Never both at once, that doesn’t work without injury.

Risks are higher with double fisting than with deep fisting:

• Higher likelihood of sphincter overstretch (temporary)
• Tears at the anus from uneven stretching
• Long-term sphincter weakness with too frequent practice

Our advice: if you want to do double fisting, ask in the community or with experienced workshop leaders first. This isn’t something you teach yourself from an article. More in our fisting school.

4.1 Rosebud / anal prolapse: what is it?

Rosebud (sometimes “anal rose” or, in a medical context, “rectal prolapse”) is a temporary anal prolapse, that is, a protrusion of the bowel lining outwards. Visually it looks like a small pink bud (hence the name).

In the fisting scene rosebud is partly seen as an aesthetic goal. Medically it isn’t harmless. Here are the facts:

4.2 Dealing with rosebud: risks and aftercare

With a mild mucosal prolapse after an intense session: stay calm, wait. The body usually retracts within minutes to an hour. Helpful: warm compresses, light massage, the bottom lies on their side.

If the prolapse doesn’t retract after 1–2 hours or causes pain: A&E. That’s not embarrassing, it’s medically necessary. Proctologists see this regularly.

In the long term, repeated rosebud practice damages the sphincter and lining tissue. Anyone pursuing it as a goal should know that it carries increased risks of:

• Chronic lining irritation
• Incontinence in later life
• The need for surgical correction

We give neither a recommendation for nor against it here. Anyone deliberately practising rosebud should see a proctologist every few years and have their sphincter status checked. More on long-term effects under Safer Fisting.

5.1 Subspace and trance in fisting

Advanced bottoms frequently report an altered state of consciousness during intense sessions. “Subspace” is a term from the BDSM scene describing this state: trance-like, dissociated from everyday life, often with altered pain perception and an intense feeling of happiness.

Physiologically, several things happen:

• Endorphin release: the body’s own opioids are released through the intense stimulation, similar to a marathon or extreme sport.
• Adrenaline spike, then drop: high at first, then the sympathetic tone falls.
• Vagus nerve stimulation: the vagus nerve is activated by the stretch pressure in the pelvis, leading to relaxation responses.
• Altered breathing: deeper, slower breathing reinforces the trance.

Subspace isn’t without danger. A bottom in deep subspace can no longer reliably communicate their own limits. What they feel as “okay” can in fact already be an injury. The responsibility therefore lies entirely with the top to read the signs and, in doubt, to stop.

Signs of deeper subspace in the bottom:

• Slurring, incoherent speech
• Laughing or crying for no clear reason
• Pale skin, cold hands/feet
• Slowed reactions
• No more answers to direct questions

When these signs come: bring the session to an end, don’t intensify. A blanket, warm drinks, body contact. Subspace fades slowly and needs 30–90 minutes to fully “come back”.

5.2 Top drop, sub drop and aftercare

What many don’t realise: the top can also enter an altered state. “Top drop” is the counterpart to sub drop, an emotional low after an intense session, usually with a few hours’ delay.

Typical symptoms in both:

• Sudden sadness or low mood
• A feeling of emptiness or meaninglessness
• Self-doubt in the top (“Was what I did okay?”)
• Exhaustion, sometimes cold-like symptoms
• Rarely: sleep problems or mild low mood over 1–2 days

This isn’t pathological. It’s a normal reaction to the hormonal rollercoaster of an intense session. Endorphins drop after the high, the body needs time to resync.

An aftercare routine that has proven itself:

1. First hour: physical closeness, blankets, warm tea or juice. No smartphone, no external stimuli.
2. First night: both stay together or phone again late at night. Driving home alone right after an intense session is not a good idea.
3. Next day: a short check-in. “How are you?”, not superficial but genuinely meant.
4. 2–3 days later: reflection, eating together, talking about the session. What was good, what would be different.

Anyone who regularly fists at an advanced level should not treat aftercare as optional. It’s part of the practice, not an add-on.

6.1 Poppers and chems in advanced fisting

The topic is polarising, but we deal with it pragmatically. Various substances are used in the scene, and the reality is that many advanced bottoms use at least poppers.

Poppers (alkyl nitrites): relax the smooth muscle and can ease the stretch. Duration of effect 2–5 minutes. Important points:

• Never together with erectile-dysfunction medication (sildenafil, tadalafil etc.), a drop in blood pressure that is life-threatening
• Not with cardiovascular disease or glaucoma
• Hands off if you have a methaemoglobinaemia risk (e.g. certain forms of anaemia)
• Fresh bottles last 1–2 months, after which the effect is markedly weaker

Other substances (chemsex / PnP): GBL/GHB, methamphetamine, mephedrone and others are used in the scene. That’s a separate, complex topic with considerable health risks, physical, psychological and legal. We give no guidance on it. Anyone practising in that context should turn to specialist support services (in the UK e.g. the Terrence Higgins Trust, London Friend’s Antidote service, or your local NHS sexual-health and chemsex service).

But what we do say: fisting under chems is objectively higher-risk. Pain perception is dulled, injuries are noticed later, the safeword doesn’t work reliably. If you fist in that context, tell a sober buddy and agree check-in intervals.

6.2 Pain, limit, injury: where are the lines?

One of the hardest questions for the advanced: how do I tell the difference between productive stretching and injury? Here’s a scheme that has proven itself in our workshops:

Anyone fisting at an advanced level should have this table mentally ready. In the heat of a session, people too often “push through” where they should stop.

7.1 Equipment for the advanced

For advanced sessions, investments are worthwhile that are still unnecessary for beginners:

• Sling: for longer sessions and optimal positions. A decent sling suspension costs £180–450. Mobile travel slings start at around £70. Probably the only purchase where “the bottom is left hanging” is a mark of quality.
• Shower douche attachment: instead of a 200 ml bulb, a continuous water flow. Allows more thorough cleansing, especially important for deep sessions. £25–90.
• Special lube pumps: allow one-handed refilling during the session. £13–25.
• High-quality powder lube: anyone fisting for several hours needs masses of gel. Various powder lubes are common in the scene, such as FFUCK Dust or comparable products.
• Nitrile rather than latex gloves: tougher, less irritating with latex sensitivity, hold up even in long sessions.
• Plug for aftercare: a smaller plug after the session lets the anus contract slowly rather than abruptly.

7.2 Long-term effects and the pelvic floor

The question “does fisting cause lasting damage?” is fair. Here’s the honest answer, based on medical studies and experience. A large survey of over 21,000 gay and bisexual men found an association between very frequent or extreme anal play, including fisting, and higher rates of faecal incontinence as well as reduced sphincter pressure. The effect is dose-dependent; causation, however, is considered not conclusively proven, because different practices overlap and the data is limited.

Anyone fisting at an advanced level 1–2 times a month: statistically no measurable long-term effects. The body recovers fully.

Anyone having intense sessions weekly: slightly increased risk of sphincter weakness in later life. Avoidable through consistent pelvic-floor training.

Anyone having extreme sessions several times a week (deep, double, rosebud): a noticeable risk of incontinence and lining damage. Here regular proctological check-ups are necessary.

Pelvic-floor training is advisable for every advanced practitioner. Concrete exercises: Kegel exercises (tensing the anus as if holding back stool), the bridge position from yoga, targeted pressing and relaxing. 5–10 minutes daily is enough.

If symptoms appear (incontinence when coughing or sneezing, persistent burning, frequent irritation): see a proctologist. Early intervention is considerably more successful than late.
