I agree with misterW in not getting emotionally invested before the first meet.
I tried match.com unsuccessfully. I think it’s too easy to mass send out connections to people.
Chemistry.com I thought was much better, since it only gives you 5 matches a day that you have to thumbs up or down. I met my current girlfriend on there, we’ve been dating a year.
I’m 27M and feel there was a bit of a role reversal because I would get tons of requests from females. You definitely get all types, and I found my self being incredibly picky (since I was just supplementing that with meeting people through conventional means).
I’m also a big fan of meetup.com. It’s not outright for dating but a lot of single people use it to find clubs and events outside their normal social circle. I used it to find a running club and boy are there a lot of attractive girls there!
If anything, sign up as a confidence booster. When I was getting all these emails from girls it had me more confident when meeting girls elsewhere.
