Not to go against your good post, Just as a matter of principle, I refuse to spend money on meeting and getting to know women when there are plenty of them out there for free.

A free verison I've been on is Okcupid.com never had much luck on there personally or
Vampirefreaks.com (which is only really good if your a goth/industrial / metaler like myself) which while isnt a dating site has gotton my quite a bit of sex over the years
