A good writer can write any kind of character. Man, woman, trans, black, white, asian, etc. All you have to do is a bit of research and most of all, avoid stereotypes. When you put them in a box is when you start showing your true colors. Like a writer who thinks women are beneath males will portray her as being submissive to them regardless of power dynamics. Animals don't rape humans, therefore a dog should not be dominating one. Nor should a boy be dominating a grown woman (especially his mother).
Sorry, but I have little faith in how you're going to handle femdom from Myriam's point of view. The fact that you make the options that boost her dominance the non-sexual ones speaks volumes. It tells me you're the kind of person who thinks femdom means footjobs and CBT instead of facesitting and cunnilingus.
And there it is, like clockwork. There's always the guy who thinks anybody advocating for better female characters, or doesn't jive with the male characters presented, must be a woman. And one who hates men. Well that's where you're wrong. I'm not a woman, but I do hate men. And I hate whenever a female protagonists has to share her story with them. Which happens all too often via writers illustrating what every man who crosses her path is thinking. You don't see that happening often with male protagonists. So it's particularly egregious when a female protag has to momentarily relinquish the agency she has over her own story to a nobody like the pizza guy or that spying store clerk.
There are several points I agree with you on, but you come off like such a prick I don't want to.
