Fisting

What is fisting?

Fisting (also fist fucking or handballing) is inserting one or both hands into the anus or the vagina. The hand does not go in as a fist: it bends only once it is inside, and often reaches the wrist. Medically that is called brachioproctic or brachiovaginal insertion.

How fisting works in practice

Slowly, and in steps. According to the encyclopedic description of fisting, people first use toys to stretch, and for anal fisting rinsing out beforehand is common. The hand comes after, up to the wrist.

What the scene calls bottom training is exactly that build-up. In Culture, Health & Sexuality, Martin interviewed eight men in the receiving role and found four themes: training the body, training the headspace, learning what pleasure is here, and playing by rules.

The jargon is precise. Punch fist is the hand that goes in already balled, double fist the one with two hands, and rosebud the intestinal wall that prolapses from anal play.

Why the body sets limits here

Because the anus is not built for what is being asked of it. In Archives of Sexual Behavior, Chen and Kalichman lay out why receptive anal penetration can hurt: the type of epithelium, the tension of the sphincter, the absence of its own moisture, and the angle between anus and rectum.

The same review sums up that stretching the anus can lower the resting pressure and disturb both the inner and the outer sphincter. So not a moral warning, but a muscle beyond its size. That is why pace matters more here than nerve.

Why people do fisting

For the degree of openness, and for what it takes to get there. Fisting is one of the few practices where nothing can be skipped: it only works if someone relaxes, and relaxing cannot be forced.

• For the one receiving, the payoff is in the build-up. Martin’s participants describe their training not as a means but as something that shapes their view of pleasure and risk.
• For the one doing it, fisting asks for an attention that few other practices ask for: with your hand you feel directly what is happening.
• For a couple, the preparation is the point. Agreements, pace, stopping without losing face: whoever learns that here has something to use elsewhere too.

Fisting is simply nothing for many bodies, and that is not a shortcoming. The research is also almost entirely about men who have sex with men; about women and couples, little has been measured.

What has been measured about the risks

Three things, all three with an asterisk.

Fecal incontinence. In The Journal of Sexual Medicine, Garros and colleagues asked 21,762 men about involuntary loss of stool in the past month. 8 percent reported it, rising with the frequency of receptive anal sex: 12.7 percent at least once a week against 5.7 percent at never. In the multivariate analysis, fisting was associated with it at an odds ratio of 1.61. The researchers name their own limitations: a convenience sample, and incontinence measured over a single month.

Transmission. In Annals of Hepatology, Ramirez-Gonzalez and colleagues compared 175 men with HIV and hepatitis C against 159 with HIV alone. Insertive fisting was independently associated with hepatitis C, adjusted odds ratio 2.62. The confidence interval begins at 1.01, so the link is real but shaky.

Perforation. Chen and Kalichman describe intestinal perforation after manual anal penetration, with abdominal pain and anal bleeding as the complaints it presents with.

What fisting is not

“It is BDSM by definition.” No. Fisting is a penetration practice with no built-in role division. That the scene knows it comes from the leather tradition, where it is called handballing: according to the encyclopedia, a word that points more to intimacy than to violence.

“A fist goes in.” The name misleads. The hand goes in flat and bends once inside; the variant where it is already balled is separately called punch fist.

“It is just reckless.” Martin questions that picture. He calls the characterization of anal fisting as risky play possibly too simple, because it overlooks the preparation with which people set themselves up for it over years.

“Vaginal is the innocent version.” Not that either. The encyclopedia names air forced into the vagina as a route to an air embolism, with pregnancy as the dangerous circumstance. So never blow air inside.

What I see of it myself

I’m Victor, a gigolo, twenty-five years in BDSM and trained as a psychotherapist. Fisting is the word where a conversation usually stops instead of starts. Whoever brings it up almost always brings it up as something they have seen and been shocked by.

The shock is about the size, while the conversation should be about the time. Months, not an evening. That is exactly the information no clip contains. I do not offer this, and that is precisely why I can talk about it openly.

What you can do yourself

• Count on months, not on one time. Bottom training is the reason it works for some, and there is no shortcut.
• Use far more lubricant than you think you need, and top it up. The absence of its own moisture is, according to Chen and Kalichman, one of the four reasons penetration hurts there.
• Cut your nails short and put on gloves. The encyclopedia names gloves, lubricant and short nails as what lowers the risk; those gloves come from the AIDS campaigns of the eighties.
• Stop at pain, not at blood. Pain comes on time, blood is too late.
• See a doctor for abdominal pain, ongoing bleeding or fever after anal play, and say what you did. Those are exactly the complaints that point to a perforation in Chen and Kalichman.
• Watch for loss of stool in the weeks after and put it to a doctor or pelvic physiotherapist: the sphincter is under pressure here.

On this site the broader practice is on anal sex, with the preparation already needed there, and safety in the BDSM context explains how you discuss risks.

Outside this site, the review by Chen and Kalichman is the best free overview of what anal play does to the pelvic floor, and Martin is the only study that takes the preparation seriously.

Where this fits on this site

Fisting is not part of what I offer: my no-go list says “anything with feces,” and inserting anally is nowhere on my yes list. Talking about it is fine. The page on the BDSM date explains how we go over beforehand what is on the table.
