In honor of Valentine's Day Eve, here's a site by a gentleman with a disturbing proposal for his ideal situation: a small stable of baby-mamas, who can choose to not be involved in their kids past infancy, and the right to decide the child-bearing partners of all of his future children. Why? "For a long time, I have shied away from male/female involvement, though desiring such involvement, due to my non-alignment with the commonly accepted and expected practises in this arena."
EDIT: I just looked all over this guy's site and am left feeling empty and sad and (after looking at the "Erotica" section of the Pictures) a little grossed-out. So be careful out there.
