> Try dating to find someone that definitely doesn't want kids, you'll find it slim pickings.
Just date career women. My past girlfriends don't want kids. Both were super smart lawyers, and very much in the "career woman" mindset. Their idea of a good life is to work hard, make loads of money, and spend it on a good time while traveling the world.
They primarily wanted company to do the above. I guess it depends on your social circles, or my luck (I actually want kids), but women who "just want fun" and don't want to be tied down with a family are a dime a dozen round here.
Actually finding a woman willing to sacrifice her career for motherhood, now that is rare here (London, UK).
