Vuistneuken

What is vuistneuken?

Vuistneuken (English: fisting) is inserting a hand, or part of one, into the vagina or the anus. The fist only forms once inside; going in, the hand is flat. The word is the literal Dutch translation of the English fisting and means the same thing, not something rougher.

What vuistneuken means vaginally

Slow stretching, and then waiting.

Almost all the literature on this is about gay men; the vaginal side is barely measured. What does exist are the measurements. For Human Reproduction, Barnhart and colleagues made 77 MRI scans of 28 women and measured the vagina at rest: on average 62.7 millimeters long from cervix to entrance, and in width 32.5 millimeters at the back, 27.8 in the middle, and 26.2 millimeters at the entrance.

That last figure overturns what people assume. At rest the vagina is not narrow inside and wide at the entrance, but exactly the other way around: the entrance is the narrowest point, and a hand at the knuckles is more than twice as wide. Vuistneuken is therefore not fitting but stretching, and that time cannot be shortened. The same researchers add that no single description captures the shape of the vagina.

Where the word vuistneuken comes from

From AIDS education, and not from the scene.

The Dutch newspaper archive gives five articles for this word, all five between 1987 and 1996. The oldest is in De Waarheid of 14 January 1987, in a piece arguing that it is not risk groups but risk acts that spread AIDS. There the word sits in the middle of a list: “sexual practices (such as vuist-neuken) in which vulnerable blood vessels can be damaged.” With a hyphen, and as a category in a list.

Five years later the Leeuwarder Courant reports on GGD volunteers handing out leaflets along the gay cruising areas in Leeuwarden: “But ‘fist-fucken’ (vuistneuken) is a good deal riskier.” The English word first, the Dutch one in brackets behind it to explain what the first means. That is how it has stayed.

The second half of the word is older and coarser than the practice. The Etymologisch Woordenboek van het Nederlands derives neuken from Proto-Germanic *hnukjan-, related to the Low German nöken and the Old Norse hnykkja, and concludes that the original meaning must have been “to thrust, to jerk and the like.” The earliest Dutch attestation in the current sense comes from a court report of 1653, and only in 1898 did the word make it into Van Dale. According to that same dictionary the early attestations are mostly in court reports, because the word was always considered very coarse.

So the name gets it wrong twice. No fist goes in, and there is no thrusting. The English fisting makes the first mistake too; the second is Dutch.

Why people want this

For the openness, and for what it takes.

The appeal rarely lies in the size and almost always in the build-up. This is one of the few things in bed where skipping ahead does not work, because it only succeeds if someone relaxes.

• For the woman receiving it the gain is that she sets the pace, because without her relaxation nothing happens.
• For the person doing it the gain is the feedback: no other act gives so much information per second.

Plenty of bodies do not want this, and there is nothing wrong with that. As a repair for a relationship it does not work at all.

What is known about the risk

Little, and what there is comes from gynecology.

The most recent piece is about exactly that risk. Driák, Zajíček and Pastor call vaginal vuistneuken an unusual and risky act in Česká gynekologie, and show that it can cause vaginal injury with heavy bleeding that has to be closed surgically. That says nothing about the odds, but it does say why this should happen slowly, with plenty of lubricant, and without forcing.

How often gynecologists see something like this has been measured separately. Lohner and colleagues sent all 316 practicing gynecologists in Hamburg a questionnaire about injury after consensual sex and got 115 back. 83.5% had seen such injury at least once and 59.1% more often; 28.1% had had to suture at some point and 20.8% had had someone admitted. The risk factors they named most often were menopause (37.5%) and the use of objects (19.8%). Vuistneuken itself was named by exactly one of the 115 in the free-text box. That is the honest proportion: rare in a consulting room, but it does get mentioned.

What vuistneuken is not

“Vuistneuken is rougher than fisting.” They are the same word in two languages. The Dutch one sounds coarser because neuken is coarse, not because the act would be any different.

“The vaginal version is the safe one.” Less has been measured about it, and that is not the same as safer. The case above was about the vaginal route.

“It belongs to BDSM.” There is no top or bottom in it. That vuistneuken occurs in the scene does not make it a power game; see BDSM for what does fall under that.

What I see of it myself

I’m Victor, a gigolo, twenty-five years in BDSM and trained as a psychotherapist. The Dutch word almost never comes up in conversation. Women who raise this use the English word or they describe it, and that is exactly what the newspapers above show too: vuistneuken is a word for explaining something, not for asking for something.

The question is rarely about the act. Women ask me whether it is strange that a partner wants this, or whether they are missing something if they do not. The answer to both is no, and that conversation lasts longer than the one about technique.

What you can do yourself

• Ask first whether it is about vaginal or anal vuistneuken. Two body parts, two risk profiles, and most disagreement starts with that mix-up.
• Let the receiving person set the pace, even when nothing seems to be happening. The entrance is the narrowest point, so everything there depends on relaxation.
• Call a doctor if bleeding does not stop on its own, and be honest about the cause. In the published case a tear only stopped with sutures and transfusions.
• Weigh menopause in. That is the factor gynecologists name most often as a risk for injury after consensual sex, and thinner mucosa tears more easily.
• Do not use oil-based lubricant together with a condom or a latex glove. That was already in the 1992 GGD leaflet the Leeuwarder Courant quoted, and it still holds.
• Never blow air inside. Why that is a serious risk is on fisting.

More reading about vuistneuken

On this site, fisting carries the English-language research and the figures on sphincter pressure and transmission, and anal sex describes the build-up needed there anyway. Off this site, the Hamburg survey of gynecologists is free to read and is the only one showing how often vaginal injury after consensual sex turns up in an ordinary practice.

Where this fits on my site

Vuistneuken is not on my list of services, and neither is anal insertion. Talking about it is fine, preferably before there is a plan. How an appointment is prepared is on the page about the BDSM date.
