I've started listening to this very long podcast of a women's conference, but most of it seems to be about comparing women to men.

We have our obvious differences, be they social or physical.
My own interests include having a place to discuss the meanings of roles we play and that are imposed on us.
What it means to risk our health, forgo or stall our careers to have children. Also the encroaching pressure of declining fertility with age.
Assuming we become stay-at-home moms, what does it mean to be dependent on our husbands in light of libertarian aspirations and values.
Traditional gender roles we are raised in and how that translates what skills we bring to a relationship. (ex. women are generally better at cooking or at least more interested or are trained as nuturers)
We can talk about whatever else comes up, but these are just some of my ideas.
