Basically a continuation to this thread, but from a different angle. Shifting the focus from official material to fanon material.
This started as a simple question, but now I am slowly losing the flare to write it. However, I will try end it with whatever I can still salvage out of my mind. So, let's start. Why are Touhou fans so horny? Looking online, old discussions have always placed Touhou as number #2 or #3 online in terms of the amount of questionable or explicit content. And a good chunk of it seems to be coming from Japan alone. The brief discussion with SasaMisa and Turbonator in general chat served a warmup for what will be going on here.
As i was saying. This whole idea to question bugged me since a few days ago. A simple walk through Twitter took me down a whole rabbit whole of questionable and explicit content based on a single artist's retweets. Basically, from a single person, you could end up creating an entire network of artists, most of them from JP. Before I am fully losing coherence, I will just expose my points as a series of ideas:
I guess "porn/sex sells" like the saying has always been - I was told by a friend I would be extremely surprised how much an artist can win out of two things: porn/hentai and furry art
why is there so much questionable and explicit material about child-looking characters? (not just in Touhou, but as a question in general) - I am sorry to put it so bluntly, but if Danbooru for example was to add a couple new tags, those two would be "child porn" and "fetish"
why are we craving such kind of content so much? what is the appeal to such content?
why is this so much of a Japan associated thing? At least from my perspective as a European, that sort of thing is utterly bizarre. If a convention or any sort of event was taking place here, with public of all ages, selling smut of any kind would have turned into a public outrage. However, when it comes to stuff like Comiket et al, it seems lie you can very easily sell such content, together with the whole concept of having doujins fully dedicated to just drawing hentai of that subject
out of any franchise online, how did Touhou gain so much popularity in terms of such content? is it just because of the almost total freedom ZUN has given in terms of fan materials?
did you ever had that kind of weird moment and sensation when discovering a piece of fanart you like and and is perfectly SFW actually has am NSFW version too? it feels very odd if you ask me, especially if you were only used to the safe one, and it was something you really liked
despite not having a clear source for the claim Touhou is in top 3 when it comes to the amount of smut material dedicated to any franchise, i do have a source for something else - apparently, Touhou fan art is the one the gave birth to "Ahegaokin" (and more or less the meme too) through a Patchouli image; at least that is what Know Your Meme says
going from memes to stats, I have alt least two sources - one for which I need to credit @Tenkko and one I found by chance; it comes in regards to the the amount of Touhou fan content that goes into the unsafe area on both Pixiv and the more infamous R34 (wish we also had a Danbooru/Gelbooru stat, as you could find a lot more there too)
(possibly severely outdated) R34 stats from last year in regards to Touhou content (no PC-98 stats though)
Also the Pixiv stats as offered by Tenkko + a few comments on my side
Also finally, there is this little thing (I cannot believe I had to rely on XE3G weeb for the info, despite how much I hate him as the creator of the "I want mommy" meme format and basically a huge liar). This is, at least from reading the comments, what happens when you let a hentai doujin try to do a safe-for-work project (game is Touhou Shoujo - Tale of Beautiful Memories)
The comments, knowing this dude and the kind of audience he brings in, are not so much of a surprise.
Honestly, I am not so sure why I am bothering so much anymore. I only end up looking like a failed crusader trying to have a failed fight against something I cannot defeat. But I think the simples thing would just be to sit down, relax and embrace the fandom with whatever it brings in, safe or not, in good or poor taste. But I am still curious though. It is almost pathological for me to ask questions about stuff I do not understand or might have a different opinion about. So yeah, this is the new direction in which the original thread is going. Since this is also basically some sort of fanservice, just of the more innuendo type.
