I've done pretty well on Match.com over the years. POF over here is a waste of time, in my view, but that's because there's not really any on there I'm interested in. I do have a female friend who is pretty overweight and she met her now husband on there.
Dating sites can be good, but there is a strategy to writing a good profile, and how to interact because women, especially ones that are even remotely half decent looking get overwhelmed with emails on there.
Give it a try mate. What's the worst that can happen? If nothing else, go on a lot of dates and get really good at "dating". That way when the right one comes along, you'll know how to act and it won't seem so daunting. Plus dating can actually be...*gasp*...FUN.
