Honestly, now I really am curious for that history less. I get to learn a bit more about Burma from someone living there
This reminds me of a similar discussion I have seen a long time ago. It is apparently something about people being interested to reveal more out of a character that s already wearing a lot of clothes instead of going for one that barely wears any. It is as as if we had some sort of desire - the more clothes there are, the greater the desire to see the person (or character) without them on. Which is some interesting line of though. My guess is that it causes curiosity in the mind of a human, looking to reveal whatever secret is hidden beneath all those clothes. It's basically like unwrapping a present if we are to thing of it as such.
And speaking of desires, here comes a new round of questions:
Why do people like so much seeing porn/erotic material done based on their favorite franchises? Like where is the charm coming from? Is it some sort of desire we have, or we merely treat is as just another object for satisfying our short-terms needs and wants? Could that desire for sex not be satisfied through other means? Like if you want some porn, why does it need to be about your favorite character(s)?
I am also asking because this sort of thing (the existence and commonality of spicy materials related to my favorite series and characters) is basically a new experience for me. My personal stance on such materials can be very much split into two stages: the BEFORE and AFTER finding out what Danbooru is. Until finding out that website, I could not really conceive the idea of going after or seeing so much explicit material related to the thing you like. One of my friends pretty much decided to get me into a "drunk watch of Star Wars R34 art", minus the "drunk" part - all I can say is that evening was a little difficult to digest.
Skipping a few months after that event, directly to when I found Touhou (so in like December 2020). Just as I drew my first Touhou fanart (seen in the Anime thread), and was asking by this friend why did I draw something with so small boobs. I told him a bit about what Touhou is, showed him a bit of official art, then he asked me what was the name of the character (I showed him an official art sprite of Yuyuko from PCB). Less than a minute later, what is the first thing he decided to show me? A R34 image of Yuyuko - my first taste of such content when it comes to Touhou. I was quite a bit shocked to see it, even if he intended it just as a joke and to get a laugh out of my innocence I still had at the time.
Skip about a year later, and my first discovery of Danbooru. Initially, I was not even supposed to be on that website. I was using Safebooru for adding images to my collection, and remarked that by searching "Iku Nagae" I could not find anything. Thinking there was something wrong, I decided to go for other boards. Without paying too much attention, I ended up on her Danbooru page (and also realized I had to search it as "Nagae Iku"). What was the first thing that got into my face? Pretty much any kind of R18 I could imagine - from nude pose to intercourse (both straight and yuri - Tenshi included). For a while, I pretty much decided to NOPE, and stayed on Safebooru. But eventually, I ended up replacing Safebooru with Danbooru. For the past 6 months, I have only using the latter on a daily basis, so in the end I feel like I got quite desensitized to such kind of content. Therefore, my question when it came to all this research was out of curiosity, not any kind of outrage for the existence of such content. I pretty much went from "I cannot imagine this kind of content existing/I don't really want to be in contact with it or purposefully go after it" to "alright, this exists, I guess [example fitting my mentioned requirements] looks rather neat".
Probably the creation of this thread was also the effect of simply going to Twitter one day based on a Danbooru link to check out the original artist, and saw that the artist retweeted dozens of other NSFW artists who were drawing Touhou stuff (I will be honest, some of it was rather neat, in other instances I was surprised as basically I did not know there was also an NSFW version of an image I was used to), and that made me start this question of why there is so much popularity for such depictions.
