Those are all choices that women can make, and there are certainly feminist considerations to making them.
But feminism is not about those minor little sideline quibbles.
Women (despite your "I'm all right Jacqueline" attitude) are not equal - they don't have an equal share of power, of property, of status OR (for many women in this country) do they get to make free choices for themselves.
There are women in the UK today who are treated as property, so your bland assurances that you don't feel like property, and therefore that it is silly to think about women as chattel is irrelevant to feminism are pretty offensive.
Feminism has never been about self-satisfied well-off women with freedom and choices telling everyone else that since they are happy with their lot that anyone who is a feminist is "insecure" and "over thinking". And then, mostly laughably of all, claiming that because they are a woman, they are above criticism by other women.
If you're so equal and not a victim, then accept that your ideas can be challenged. Holding simplistic and foolish opinions based on ignorance is not a "choice" that other people should have to respect just because you are a woman.
