I have not utilized any form of online dating services yet. I would be open to a possible relationship with anyone from anywhere and might well someday utilize a foreign dating service. Hey, I'm 29 and I'll be 30 before I put into time commitment into a serious search. I don't have time to deal with those women that have leftover adolescence mentality. Let's face it--American women are notorious for head games and I'm more impatient with that shit now than I was 10 years ago, and I don't know that I ever enjoyed such attitudes. Besides, a good foreign accent is a very sexy thing.
That all being said, most qualities I value could probably be found through a good American service such as eHarmony.
