Not here, but that was just cos we didn't meet any guys on here that my wife was really into (she's hell picky unfortunately). We've had heaps of interest on here but just haven't happened to get to the point of escalating things with any of those particular guys. So with that said it's hard to really tell about this site specifically, but a few seemed pretty genuine.
Fabswingers has garnered HEAPS more hits, but again, haven't actually tried to meet up with anyone from there yet.
Our guy (that things are going REALLY well with), we met on Locanto.
Hope this helps, lemme know if I can give you any more advice. And keep trying!
Best of luck.
