I’m glad for you that you’re happy and sexually fulfilled.
Just because you get off on a bimboification fetish and think of yourself (and of WOMANHOOD) as an “object to be modified and abused for others' pleasure” does not make you somehow special or empowered though. You’re not a feminist just because you’re a woman making a choice. Being able to make choices is important to feminism but that doesn’t mean all choices are feminist.
Being supportive of people’s right to participate in consensual sexual practices with other adults even if they’re unusual doesn’t mean “all kinks are equally good”. Great, you get turned on by misogyny and humiliation. Good for you. That doesn’t mean misogyny and degradation of women is a good thing though.
And look, I have fantasies that are misogynistic and masochistic too, but I don’t write about them as if they’re GOOD for me psychologically or that the thoughts are ethical. I’m not a bad person for having these thoughts or getting aroused by them because I didn’t choose my brain to be wired like that, but that doesn’t mean the thoughts themselves are good or unproblematic.
You seem to be trying to cast your fetish as being inherently feminist, and it’s not.
