Yes - I'm not sure it's a good fit for me. I prefer to date men in my church (there aren't any locally), so I was meeting people clear across the country. We'd get along fine by phone, and feel a 'connection,' but it was hard to translate that in person.
I know many people who have met and married someone they met online, though, so I say give it a try! Watch out for scammers - there are quite a few, but you can learn to spot them. Good luck!
