Elsewhere here on UKP I've spoken up in favour of Fabswingers in some previous threads.
I've had a fantastic time on Fab over the last ten years or so. Absolutely bloody brilliant. Just put the time in, and you'll get the rewards. Don't go in cynical. Be a gentleman, show pics (I only send a face pic privately, when I'm very sure of it), and most of all don't be a pushy twat in too much of a hurry to get a fuck, like 10,000 other guys on there.
I've had dozens of meets, with some real crackers whose hubbies want to show them off. Plus some very cute single girls, and then you can also delve into what your own fetishes are very easily on there (I love big tits, and fuck me Fab's delivered on that too).
As somebody above said, it's entirely different from punting.
Takes much more effort, but as far as memorable sex goes, there's no comparison.
I love UKP and successful punting, don't get me wrong, and a great meet with a good, fully-engaged girl from EG: AW can also provide you with long-lasting memories of very, very satisfying sex too.
Two different things, but don't knock Fab till you've tried it believe me.
