Dating Website Angst!

What am I, a magnet for green-card ticketers? Because I don't get out much, and I'm lonely, I have tried to see if there would be any possible connections through various free dating websites. Up to date, I have had messages from a guy from Hong Kong, 2 from India, and a 38 year old math professor from Saudi Arabia. But none from the USA, let alone my area. Am I really just not cute enough to attract the attention of those not just trying to get an American wife? Perhaps I'll try a site where I have to pay for membership....either that or I'll try the outrageous concept of actually going out and meeting people out yonder in the world...*gasp!*
