Poly Women Respond

[River]

One of my bestest friends (I'll call him Sean, though it's not his real name) told me last night that women just aren't well suited for polyamory, that it goes against a woman's basic nature when there is sexual/romantic involvement. He said he thinks women are just biologically driven to be possessive and desire exclusivity in love.

What, dear women friends, would you say to Sean? (I'll point this thread out to him at some point and he can read it.)

Edit:

Although us guys may be tempted to discuss the posts in this thread, I want to very strongly discourage men from participating in this thread at all, myself included. If need be, we can start a thread in which men and women both can discuss this thread.

And let me thank all of the women in advance for their comments. Much appreciated.
