Here's the thing though...
You're phrasing this as though these characters are actually people, making these decisions, for themselves. But they aren't. They're made up characters. They do whatever their writer makes them to do. It's like, "Yeah, I wrote this character to be slutty, but it's okay, because she likes being slutty!" and it's like, well, yeah, because you wrote her to be like that.
The person who created Bayonetta is not themselves, Bayonetta. They're not representing themself. Bayonetta's creator is a horny dude who created a fake horny naked lady who loves being a horny naked lady. And that is supposed to somehow be 'empowering', despite the fact that the character itself, literally has no power. They are fictional. They are slaves to their writer's whims. They are exactly what their writer wants them to be. No more, no less. There is no Bayonetta choosing that she really loves doing sexy dances and making her clothes disappear. A guy wrote her to be that way.
This is, of course, much less of an issue when the character creator, in a way, IS representing themself. When said women characters are actually created by women creators.
