I kind of find this amusing as, of the stories I've had published, the highest rated were the ones I did with a bimbo theme. The lowest had smart female protagonists. I wonder why this is.
Well, as a woman it's tempting to jump to conclusions. But I do think that there are 2 possibilities that might contribute to this (other than chauvanism).
As someone else stated, you might simply be better at writing bimbofication themed stories.
But adjacent to that, its possible that the demographic enjoys 'mental' bimbofication not out of mysogyny, but as a form of dominance/submission play.
Often the mental aspects of bimbofication occurs on two levels, one being decreased intelligence, the other though, being increased libido. It's possible that it's the second feature which is holding peoples' interests, and that the decreased intellect may only exist as a plot device to erode the character's self restraint, causing them to engage in more exciting activities.
Personally, I (usually) don't like stories which have bimbofication that turns women stupid. I find that to be a turn off. Not a 'deal breaker' turn off that would ruin a story for me or anything, but a turn off nonetheless. But... I do enjoy the idea of increased libido occurring alongside physical hyper-feminization. And I like the "erosion of self restraint" theme very very (very) much, I just like to see it occurring through elevated libido, or addictive qualities, rather than reduced intellect. I'm totally in love with the "unleashing the inner slut" concept itself, I just don't think that one needs to make characters stupid to pull it off well.
also, mental bimbofication can be kinda hot if looked at as a "mind control" theme.
** note: stupid-ifying a character who "has it coming" in a poetic justice sense, doesn't bother me at all.
And of course, there are some fellows who have a low opinion of women and like reading about stupid specimens. Particularly in some 3rd world countries, and/or first world areas where **37** is popular.
** another note: for those who like their bimbos "ditzy": I'm the antichrist, go away.
anyways, now I wanna read the story update...
on the topic of age demographic. I think this forum seems to average around "middle aged". But some people do look back on high school years with a sort of dishonest nostalgia (i say dishonest because really, high school sucked guys, cummon). But it can be fun to imagine a high school setting which is more fun than the one we all actually experienced, no?
And i agree with the idea that it makes for more innocent, less complex, characters that are maybe a bit easier to write convincingly. Plus it's a structured setting which everyone's familiar with. You describe a school... BAM, everyone has a mental image of it. You describe the offices of the Bovine Research branch of Mega-Corps... well, you need to be a lot more descript to paint an equally vivid image for the reader.
and what the f*ck is up with spellcheck today? I think it's vocabulary has been severely bimbofied. And I don't really have time to teach it more english today... oy.
