Author notes: Retroactive explanation of the intent behind the rules

There are two story branches based on the previous chapter. And both are different from the intent of the rules. This probably means I explained the rules badly, so I will try better (this doesn't mean the already written chapters should be changed, if it's too much work).
I might end sounding repetitive, but I just want to be thorough.

There is no institutional sexism, or systematic discrimination of women. Individual people can still be sexist.
Women are just as respected as men. But that can still mean "not respected at all".
The other rules make it possible for people to harm women (and only women) in sexual ways not covered by law which forbids legal and systematic discrimination.

Everyone has a fetish for submission, humiliation, and ****. Men have it as something happening to women, women have it both as something happening to them, and to other woman (so any woman might be aroused by seeing another woman ****, or even by participating, as all are bisexual). This doesn't remove fetishes people might already have (like a woman who has a fetish for humiliating men. After the change, she will have fetishes for humiliating both men and women).
Having a fetish for it means women are aroused by it happening. Just because they are aroused doesn't mean they actively want it to happen, but some might. In any case, there is an element of enjoynment even if the situation is completely ****, and even if the woman otherwise hates it.
Not all women know they have this fetish. Those who do know don't talk about it openly (unless they are the kind of person who would talk about it in reality).
Not all women know they are bisexual. Those who do know don't talk about it openly (unless they are the kind of person who would talk about it in reality). Women who in the "old world" were straight, lesbian or asexual will continue believing in it untill they see a strong confirmation (and then, again, probably not talk about it). The appearance is that the fraction of bisexual women is the same several percent as it is in reality.
Not all man know they have this fetish (though "all men are rapists/animals/sexually violent" is a common talking point just as it is in the real world).
Literal **** is not the whole of the fetish, maybe not even the main part. Groping, spanking, tickling, stripping, outfit control, name calling, and degradation (though I personally prefer it doesn't go into stuff like dehumanization and forcing women to pretend to be animals. It's on theme, and it's valid to write, but I just don't like it).

Women are not able to resist or oppose sexual advancement. Not to them, not to other women. They can still say "i don't want this", or not actively help, but they can't fully resist. If given a command (such as "tomorrow come to work without panties"), they will not automatically obey it, as though by mind control, but it is very easy to coerce them by threats, punishments, rewards, or anything else. It is harder to do the more complicated or hard the command is, and some women will not obey some commands at all (but this only applying to actively following the commands. They will still be unable to resist stuff done to them). This becomes easier to do if you already have some kind of power or authority over the woman.
(Yes, this does mean two or more women can have an all-out humiliation-war where they can harm each other as much as they want, without being able to protect themselves. I know a couple cool stories like that.)
Women don't know why it happens, and might come up with different rationalizations (but "turns out I am just a slut who enjoys it" is a common conclusion). Women who don't already have an experience with it will not know they are unable to resist sexual advances.
Those who make the sexual advances on the woman will not know women are unable to resist it. They might think "all women are easy sluts", but only if they are the kind of people who already thought so before the change. A person who tries will succeed, and so will be less discouraged in the future, which means it happens much than in the real world, but that doesn't mean theywill think it always works. A person who harassed/**** a lot of women might think "wow, I have huge luck", and might even theorize "all women are like this", but will never know for sure that this is true, will never know for sure that any random woman found on the street will be just as submissive. Literal magic prevents people from coming to that conclusion (why? Because if people did know this, it would become boring). They might come to smaller conclusions like "wow, this town/family/company" is freaky, and then keep it secret.
A man will not just **** a woman the moment he realizes he is aroused and wants to **** her (in reality, a bunch of people do in fact have a fetish for **** people, but still never do it), unless he has reason to realize it will works, and a feeling that it will be kept secret. Though often there is a gradual escalation of "i just said something as a joke, then touched, then stripped, then ****, and now will keep ****".
If other writers want to add the rule "every time a man is aroused by thoughts of **** or harassing a woman, he will proceed to do so", you can, it makes perfect sense, but that's an additional rule, not something my list of rules already contains.

Someone trying to sexually exploit a woman will try to keep it in secret. Even if it's a guy who decides to share her with his group of friends, he would try to keep it secret among that group of friends. He might not try very hard, and fail, but he will try, people will treat it as something secret and shameful, because it is. People will try to keep it from "the rest of the world", even if it means a big growing bubble of people, so big it might as well be "the rest of the world" (I think it would be rare. Unless it's some darkweb site that leaks session of sex with a celebrity, or something, and then thousands of people are a bubble keeping it secret).
And the secrecy is not pointless. If some people see real **** or harassment, they would be aroused by it, because everyone has the fetish, and might take advantage, but they might instead report it (there is this thing called "morality" or "conscience"). Rapists will still get arrested (just a very small fraction of them). And the people who do report it to the police, or friends or family and such, will try to keep it secret from "the rest of the world" (which is realistic. Many communities have some cases like this, that a **** happened, everyone agrees it's wrong, everyone hates the person who did this (if they know who it is), but don't tell it to outsiders. The chance your mother was sexually harassed somewhere in her life is very high).
A lot of people might have suspicions, about a lot of stuff. "This women is sceretely a slut", "this guy is secretely a ****", "i think something weird happens in the boss' office" after hours, etc. The suspicions don't usually grow further, without hard evidence. People are a bit oblivious and tend to write off small stuff like "this woman's skirt was torn in public. Wow, this happened yesterday too, what a coincidence". People will often notice humiliation, and even take (plausibly deniable) part in it, as long as it's not obvious it was someone's direct fault (by combination of "actually not noticing" and "I suspect something, but no one else does, so I will just keep quiet and enjoy the show"). "All love to laugh and the humiliation of other women, untill it's their turn" is a rule I considered adding, but I am not sure how necessary it is, and also suspect it interferes too much with the appearance of the normal world.

The rulebook story by takemetothepron had a rule preventing long-term trauma.
I thought about something like this. It would not decrease any negative emotions, but will just mean that the emotions are temporary, and a woman is not permanently traumatized by things that happen to her (which is good, because bad stuff will probably continue to happen). I decided not to add it, for three reasons. One, I am not sure how to phrase it. Two, I already added one rule (bisexuality) to the original three, I don't want to retcon even more. Three, this is a fix for something that doesn't really happen in the stories, because the stories will probably not be long term enough. The immediate reaction would be exactly the same. And I don't expect anyone to write stories with perfect psychological realism, so a rule that says "you can keep ignoring the thing you were already ignoring, but now with more justification" is not that important. If you want to, you can imagine and write as if I added it to the list. Maybe even outside the "culture stays the same" clause. That **** is bad, but never causes women permanent psychological damage, might not change culture, or change it in ways beneficial to the story, or be something there is no conclusive scientific evidence about.

That's mostly it, I think.
There might be typos here, but hopefully I will fix them in several days.
