How to Self Suck: What Autofellatio Actually Takes

☆ Prefer the Gay Blog on Google

Self sucking comes down to 3 physical factors. How far your thoracic and lumbar spine will flex, how long your torso is relative to your legs, and how far your hips will fold. Only the first of those responds to training. Below is the step-by-step approach to giving yourself a blowjob, the positions ranked by difficulty, and the signals that mean stop immediately.

What actually decides whether you can

The distance between your mouth and your penis is a matter of proportion, not effort. A short torso with long legs leaves less ground to cover than a long torso does, and no amount of practice changes that ratio.

The second factor is spinal flexibility, specifically through the thoracic and lumbar regions. That is where the curve comes from that brings your head down. Your hips need to fold deeply so the pelvis can travel towards your upper body.

Belly volume can take up the space between ribcage and pelvis, so it plays a part. That factor has never been quantified, though, and no source weighs it against spine and proportion. If it does not work for you, the reason is almost always the ratio you were born with rather than your weight.

Your neck is not a limiting factor. No source names it as one. It is, however, the single most dangerous part of the movement, which is covered further down.

How to self suck, step by step

Work through this in order. Skipping the preparation is where injuries come from.

1. Warm up dynamically for a few minutes. Move through your full range: gentle spinal rolls, knee-to-chest, hip circles. Movement, not holding.
2. Empty stomach. A full one takes up exactly the space you need. Leave a couple of hours after eating.
3. Start supine. Lie flat, put a pillow under your lower back, draw both knees towards your head and let the pelvis follow slowly.
4. Go by millimetres, not by force. The end range should feel like a stretch and never like a pinch. Sharp pain means the position is wrong, not that you are close.
5. Breathe out on the way down. Exhaling empties the ribcage and buys you a little more room than holding your breath does.
6. Stop at your limit and hold briefly. Then come out of it slowly, one segment at a time.
7. Stretch statically afterwards. Roughly 30 seconds per position, hamstrings, spinal erectors and hip flexors.

Most men who get there need weeks, not an evening. Reaching the glans is the realistic target, and taking more than that is rare even among those who manage it.

The number everyone quotes that does not hold up

Nearly every article on this topic repeats the same figure: only 2 or 3 men in 1,000 can reach themselves orally. It gets credited to Alfred Kinsey’s 1948 survey.

That attribution falls apart on inspection. The footnote behind the sentence leads not to Kinsey but to a 1954 psychoanalytic review by Guy and Finn describing exactly 2 cases. That is a case report, not a population survey. In Kinsey’s original work, based on roughly 5,300 men, the figure does not appear. What it does say is that a considerable portion of men attempt it, particularly in early adolescence. That describes attempts, not a success rate.

No sound modern prevalence data exists either. So any hard percentage you read on this subject rests on nothing. All that can honestly be said is that it is uncommon.

Warming up and stretching, in the right order

Spinal mobility responds to training. In older adults, range of motion improved measurably over 8 to 10 weeks with 3 sessions per week of 20 to 30 minutes. Nothing shifts in a single week, but the idea that flexibility is fixed at birth is wrong.

The order matters and is usually given backwards. Dynamic movement belongs before the effort. Static holding belongs after it.

Long static stretching immediately beforehand works against you. Past 60 seconds of hold per muscle group, measured performance drops by 4 to 7.5 %.

For the stretching itself, 30 seconds per position is enough. The classic study on hamstring flexibility found that holding longer, or repeating more often across the day, adds nothing. Focus on what folds you forward: hamstrings, spinal erectors and hip flexors. Yoga sequences built around spinal flexion cover all 3 at once.

Positions compared

Four positions are in common use, and they differ sharply in difficulty and in risk.

Supine is where everyone should start. It is stable, you can abandon it instantly, and the pillow does real work.

The shoulder stand rolls further back until your weight rests on your shoulders. This is where the mistakes happen. Your weight must never come down on your neck, since the cervical spine is not built to carry load in that degree of flexion.

Side-lying gets mentioned rarely but suits some people better, because the spine curves differently there. It costs nothing to test.

When to stop immediately

Extreme cervical flexion can compromise blood flow through the back of the brain. The symptom picture for that is documented and unambiguous.

• Dizziness or the sense that you are about to black out
• Any visual disturbance
• Tingling or numbness in your arms or legs
• Ringing in the ears
• Pain radiating into an arm or a leg

Any of these means you unwind the position at once and slowly. Radiating pain points to pressure on a nerve root. That is not a stretch sensation and pushing through it makes it worse.

A documented case from 2019 shows how serious extreme flexion can get: a patient sustained a fracture-dislocation at the fifth and sixth cervical vertebrae during sex, caused by neck hyperflexion. The spinal cord was compressed and surgery was required. No case report exists for autofellatio specifically, but the mechanism is the same.

Anyone with a known herniated disc should leave this alone entirely. For that group the risk sits out of all proportion to the reward.

If it never works

For most men it never does, and the reason is a set of proportions that will not change. Even among those who manage it, reaching the glans is usually the whole of it.

The practical alternative is a masturbator, which reproduces the sensation and asks nothing of your spine. If your interest is really in improving oral technique on a partner, the deep throat guide and the piece on the gag reflex cover that ground. For solo technique generally, see the wanking basics.

Frequently asked questions about autofellatio

These 8 questions come up most often around self sucking. They cover feasibility, training, positions, risk and the prevalence figure everyone repeats.

Can any man learn to self suck?

No, and for the large majority it stays out of reach permanently. It depends on thoracic and lumbar spine flexion, on torso length relative to leg length, and on hip mobility. Only flexibility responds to training, and that has an anatomical ceiling. A long torso is not something practice overcomes.

Is it true that only 2 or 3 men in 1,000 can do it?

That figure is everywhere and it is unsupported. It gets credited to Alfred Kinsey’s 1948 survey, but the footnote actually leads to a 1954 psychoanalytic paper describing exactly 2 cases. The number does not appear in Kinsey’s original work. No reliable prevalence data on autofellatio exists to this day.

How long does it take to get flexible enough?

There is no dependable answer, because starting points differ so widely. What has been measured: spinal range of motion improved over 8 to 10 weeks with 3 sessions per week of 20 to 30 minutes. Whether that is enough in your case is settled by anatomy rather than by persistence.

Do I need to lose weight for this to work?

That is the most common misconception on the subject. Belly volume can reduce the space between ribcage and pelvis, but that factor has never been quantified and no source weighs it against spinal flexibility and body proportions. A full stomach right beforehand gets in the way measurably more than a few kilos do.

Which position should a beginner use?

Supine, with a pillow under the lower back. It is stable, you can stop at any moment, and the pillow genuinely shortens the distance. The shoulder stand is the next step, and there the weight has to rest on your shoulders rather than your neck. The standing version is unreachable for almost everyone.

Is autofellatio dangerous?

Done sensibly it is not. The risk sits in extreme cervical flexion, which can compromise blood flow through the back of the brain. That announces itself through dizziness, visual disturbance, tingling and ringing in the ears. A documented 2019 case describes a severe cervical spine injury caused by neck hyperflexion during sex. With a known herniated disc, skip it.

Why should I not stretch statically beforehand?

Because it reduces what your body can do. Past 60 seconds of hold per muscle group, studies measured a performance drop of 4 to 7.5 %. Dynamic movement through the full range belongs before the effort. Static holding, around 30 seconds per position, belongs after it.

What are the options if it never works out?

A masturbator reproduces the sensation and places no demand on your spine, which for most men is the realistic answer, since the limiting factors are proportions that cannot be trained away. It is worth knowing that even successful attempts usually reach the glans and no further.
