Lately people have been telling me gender identity is a thing you feel - that you can 'feel like a woman', for example. But I legit don't understand what that means. Does feeling like a woman mean you want to wear women's clothes? Or have a vagina? Or get sexually pursued?

Like what is it about womanhood that is the thing that people 'feel like', in such a concrete way that they know that's what it's like to feel like a woman? I'm a woman and I have no idea what it feels like (besides what I listed), so I'm extremely confused about this.
