So I know this has been discussed in the past, and usually the same things result each time, but I actually thought about giving this a spin I'm not aware we've used before to look at it. In short, what I'm asking is how many people in the greater diaper community there are?
First, my methods. I decided to run google searches for a number of different keywords for various sexual kinks, and record how many hits each one got me. Be warned: I searched for some pretty sexually explicit things outside of what's the usual territory here.
So here's what I came up with. Each pair represents the key word exactly as I searched, and the number is google's estimation of how many hits were returned.
The internet is basically a free market system. So I'm going to say that the number of hits on each keyword(s) is a measuring stick for how much interest there is in a given subject: people who want information, people who want sexually arousing material, and any interest otherwise.
I'll add a few caveats. First, the search for incest probably generated a number of false positive hits- I'm sure many people are searching it as the result of abusive incestuous relationships along with people searching for it for sexual arousal or as a result of being involved in a positive incestuous relationship. I also ran searches for incest with various family positions (mommy, daddy, daughter, etc), each of which cut down the number of hits by about 1/2 to 2/3.
Next, I had two keyword sets involving the word girl: "girl squirt" and "girl piss". The former was because I was sure the word "squirt" would have too many false positives and I modified it with girl as squirting, in sexual terms, refers pretty exclusively to female ejaculation (which got significantly less hits). The latter was to gauge the general urolagnia community as, essentially, a community which overlaps with us. Furthermore, most people who derive sexual gratification from urination are specific to women as the object of desire, not men.
The terms sex, lightbulb fetish and balloon fetish were there to give scale to the numbers. I assumed that the number for sex gives scale to most if not all people on the internet looking for sexual material. On the other hand, lightbulb and balloon fetishes are ones that while documented are known to be exceedingly uncommon.
Last, let's take a look at the four *BDL-themed searches I ran. I'm including "girl piss" in that. There's overlap between the *BDL community and the urolagnia community enough, IMO, to lump it in. Adult Baby returned waaaay more hits than did the other three searches. My first inclination was to chalk this up to false positives- people looking up information on having kids, child rearing, etc. Yet when I clicked through and scanned pages of the search, just about everything there was *BDL related, so that doesn't seem to be the case. More on that later, though.
Now let's look at what these numbers mean. I'm not so much interested in what these numbers mean so much as I am their size relation to one another. If there are X webpages extant or classified by google or whatever on topic A, then that corresponds to a certain level of public interest in topic A. If there are the same number of whatever it is that exist for topic B, then there's probably the same level of public interest in topic B. That's the goal of this. In any case, I'm going to simplify the process by referring to the numbers as hits by google.
That all said, let's start!
So google returned about 600M hits for sex. That's our baseline for public interest in sex. When we go to topics that are more specific but still have a very mainstream appeal, oral sex, anal sex, cum, the number markedly drops. I note that BDSM and bondage returned similar numbers. While they're still considered rather kinky, I also think they're relatively mainstream. Not many people bat an eyelash at a partner who wants to be spanked or restrained or whatever.
Where this starts to get interesting is where I put in the three bestiality searches. I mentioned dogs and horses specifically as these are the animals most often involved in bestiality. I admit being a bit amazed by the number of hits, I didn't expect so many. The reason I find these interesting is that Alfred Kinsey actually provided in his landmark studies numbers of men and women whom reported sexual contact with animals which was more than incidental: 8% of men, 3% of women, around 5-6% of the public overall. That may not seem like a lot, but consider that it's 1 in 20. Think back to a class in high school. It's likely that about one person in each of your classes was or has since been having sexual relations with an animal. And if anything, those numbers are under reported- something I actually consider rather likely. And what do you know, the average number of hits for the three bestiality searches I ran comes out to be roughly the same percentage of the number of hits returned for "sex." So it looks like my system has some real numbers backing it up.
Now for the good stuff. Infantilism and diaper sex both turned back similar numbers. Girl piss turned back more, I'm presuming because it includes a number of people from our community plus a number of people outside our community as well. As for Adult Baby, I'm not sure how to consider the sheer discordance in hits returned when I failed to find a single false positive in a brief scan. In any case, I think that we can take it as a sign that the numbers returned by the three other searches are either correct, or too low. But they certainly aren't too high. This is where it gets a little crazy. If the numbers I got from bestiality are used for comparison, it seems that the overall population of people sharing in some sort of elimination-centered interest- sexual gratification from pee or poop, interest in diapers (sexual or otherwise), adult babies- consist of somewhere between 1 in 50 to 1 in 40. That's not really high. But really, that's a heck of a lot higher than I ever imagined it might be.
Last, take a look at my queries for lightbulb fetish and balloon fetish. Both of those clocked in at exceedingly low numbers, low enough that they might even be a bit fuzzy. But let's examine them on a relative scale. Interest in diapers (and other related) items I detailed seems to be around 25 to 50 times higher than them. That's about where it should be.
So this is rough, but honestly, it strikes me as a fairly reasonable assumption. Thoughts?
