Blown away: A beginner’s guide to inflation fetishes

In previous blogs I have briefly mentioned various forms of inflation fetishes. In my blogs on fat fetishes and alvinophilia (belly fetishism) I noted that some fat admirers encourage their sexual partners to engage in inflation activities (where individuals inflate their abdomen with air or liquid so their abdomen is distended). Belly inflation is part of the wider practice of body inflation, and involves the practice of inflating (or sometimes pretending to inflate) a part of one’s body typically for sexual gratification. For some, this may be connected with sexual arousal from the receiving of enemas (i.e., klismaphilia). According to a Wikipedia entry on fat fetishism:

“Inflation refers to the practice of inflating (typically with air or liquid), until the abdomen is distended, in such a way that it simulates a stuffing or bloating, but without food”.

In my blog on scrotal infusion I described the sexual practice in which fluid (usually saline solution) is injected into the scrotal sac as a way of making it balloon in size (which is why the practice is sometimes referred to as ‘ballooning’). A very similar practice is scrotal inflation in which air (or other gases) are injected into the scrotal sac. As I noted in my previous blog, both scrotal infusion and inflation are potentially dangerous, and individuals engaging in such acts are at risk of scrotal cellulitis, subcutaneous emphysema, Fournier’s gangrene (a type of necrotizing infection or gangrene usually affecting the perineum), and/or air embolism. As far as I am aware, there is no academic or clinical research on the practice although there are a number of websites dedicated to this practice (e.g., Here are a few online accounts I came across:

Extract 1: “Ever since I was pregnant, I constantly fantasized about having that big round belly again. I used to watch pregnant porn and try to push my belly out and rub it but obviously wasn’t the same. I recently came across inflation. I never heard of it before nor thought it was possible, and it turned me on so much. I just tried air inflation with a fish pump for the first time yesterday, and it was such an amazing feeling to have a hard tummy again. I rubbed it up and down it was amazing but it was a bit crampy at times. I loved the pressure, my tight belly…I know I’m going to have to practice at it more…I want to get to a point were my belly looks pregnant with out all the cramping…I haven’t been able to talk about this to any one nor my husband. I think he’d find it extremely weird”.

Extract 2: I have an inflation fetish myself. Every now and then – which is starting to become daily – I usually inflate my stomach with air or water. I occasionally chug [almost] a gallon of milk or water with salt in it – chugging too much water can be poisonous, so always put some salt in it to balance your electrolytes. I find it very arousing to get a rock-hard stomach and I want to continue to make my stomach bloat bigger and rounder, yet maintain my abs. It’s a fun challenge”.

Extract 3: “I have the same fetish. I’m a gay guy, and I prefer belly expansion in particular. I think this fetish is somehow tied to the weight gain fetish that the internet and media has exposed in recent years. I, too, have a weight gain fetish. However, I enjoy helping or watching a partner partake in weight gain, but not myself. Getting back on the subject, though I do enjoy inflating myself. Whether it be through bloating with water, air enemas, or water enemas. Water enemas have become my personal favorite method, plus they’re actually healthy and cleanse your colon. I have noticed a lot of people with similar fetishes though. Everyone has their own niche of what turns them on”.

Obviously I can’t verify the veracity of the claims made by these individuals but assuming they are true and accurate admissions, they demonstrate that inflation fetishes exist and that there appear to be overlaps with other sexual fetishes and sexual paraphilias (such as fat fetishes). However, we know nothing about the incidence, prevalence, and the development of the fetish. In one of the many online fetish lists, one of them on the Thumbpress website (’10 strange fetishes that don’t make sense’) said that one of the inflation fetishes (‘air pumping’) was “quite disturbing…perhaps as disturbing as klismaphilia” and involves pumping air into the anus to the point that it expands the belly. The website’s critique was the practice was “unhealthy, dangerous and ridiculous”. On another fetish list on the Cracked website (‘5 ridiculous [safe for work] fetishes’), the article notes that:

“[Inflation fetish] is kind of like the balloon fetish, but with a fun twist. Instead of blowing air into a party favor, you stick a bicycle pump inside your danger zone and inflate your own body until you feel like you’re going to burst. You get the farts for hours after you do it, and these guys talk about that like it’s a plus. Normal people get a stomachache after swallowing air and trying to burp, so we think it’s pretty easy to see what these guys are going through. Besides having massive online communities dedicated to the practice of filling tummies with air, there are also millions (OK, tens) of YouTube accounts whose sole purpose is to show videos of stomachs growing slightly larger”.

One aspect of air pumping that should never be attempted is vaginal air pumping. On one sexual ‘agony aunt’ website (Go Ask Alice), one man asked whether blowing air into his girlfriend’s vagina could kill her. The response by ‘Alice’ asserted:

Yes, it’s a true but very rare occurrence. When air is blown or forced directly into a vagina – without allowing any air to escape – an air embolism (the abnormal presence of air in the cardiovascular system) could form, which can be fatal. Women who are more at risk for this unlikely possibility are those whose pelvic vessels are enlarged (meaning, increased blood supply to the vagina) due to a condition such as trauma and possibly pregnancy. So, if a very large amount of air were to be blown or forced into their vaginal canals, it’s possible that the air could enter their bloodstream, causing a blockage in a blood vessel. As a result, some of these women, perhaps including the pregnant women’s fetus, may experience complications. In extraordinary cases, some of these women (and the fetus) may die if the embolism travels to the heart or lungs”.

The lack of empirical research into inflation fetishes is either because they (i) are viewed by the academic and clinical communities as a trivial research topic, or (ii) have not (as yet) caused any problems among its adherents. If papers do end up being published it may be as a result of when things go horribly wrong (i.e., someone dying).

  1. Hi there.
    I read your article and found it interesting.
    As a member of the “belly inflation community” out there, I can tell that what those posts you found say, is true.
    I myself, have experienced belly inflation with other guys’ bellies and with my own.
    I still can’t understand or explain myself how did I get into this “fetish”.
    What I remember since I was a little kid is that I felt attraction to the abdominal area of the human body, whether it was male or female abdomen. With the time, that attraction inclined more into the male abdominal area.
    As for the belly inflation, I remember randomly finding a belly inflation video in youtube back on 2006 (before Goofle took control of the site and started deleting many “mature” content videos). In the video, there was a guy, on his bed with his exposed belly. His face was never seen. Suddenly you can hear the sound of some kind of machine, like a compressor which actually was that. His belly starts instantly growing as he kept going and making short pauses. I don’t know why, I don’t know how, but this video made my heard beat go faster, I got aroused and i liked what I was watching but my mind was not believing that such a thing was possible. After that video I started looking for similar stuff and found more and more. With the time, more and more new guys (and a few girls) started to appear on youtube, practicing belly inflation. I kept myself hidden as a watcher until I met a guy that caught my attention. I started to chat with him via youtube inbox and talked about his videos and of course I asked as many things as I could. He seemed to be very experienced in this, although he was only one year older than me. We became online friends until we took it to the next level. We met and among other things (like getting to know his country, his city, his culture, etc), he let me inflate his belly one night. I couldn’t believe this was happening. I was doing this to a guy for real and I could experience it for real.
    We became more than friends and eventually into a relationship that lasted a couple of years. During that time, he kinda got me into inflate myself. I started doing it but most of the time, it hurt a little. I’ve been doing it but not so often. Sometimes I can really feel something weird that arouses me a lot. Sometimes I just feel a little bit of discomfort and nothing else.
    I still can’t explain why and how. I just find it arrousing, getting my belly inflated and inflating someone else’s belly. But the 2nd one gets me going.
    I really would like to find out why do I and so many other guys and girls find this practice exciting and arousing. Is it wrong? Is there something wrong in my head?
    I once thought about telling about it to a psychologist, but I was really ashamed and afraid that he would said I was crazy or sick or something.

    Hope there are more answers about this weird topic in a near future.


  2. Would the air embolysm problem with vaginal inflation be solved with water inflation or a liquid that is similar to the contents of the blood.

    • No. Still has air in the water. I would say its too risky. There are other ways you can inflate through the vag that don’t require that.
