I have tried FabSwingers and to be honest if you are over 40 it isn't worth it. You spend all your time messaging 'reasonable' looking women and never get a reply. Sometimes you even try the really large old women you would run from if you met in the pub, and still you are not their type. On their profiles they have shopping lists and demands that mean they want Brad Pitt but they look like Nelly the Elephant.
Eventually you do get one or two to chat, so you spend weeks convincing them to 'Go For a Coffee' but they suddenly disappear or you seem to find a strange way to upset them so they can call it off.
Once in a blue moon, you get to meet a 'reasonable woman' and then you spend the evening doing a 'Social' this means you pay and they don't ...in any form. Now this could cost you a couple of hours and a meal, so lets say £50+ and you have spent weeks getting to this point, and you are so desperate although she looks like a stuffed pig, you might ..you just might...
Eventually you do get a second date, you have to take them out again, another £50+ and you get to taken them home, omg for the night. so you get a little sex, but now you have snoring beast woman in your bed, and you have to drive her home in the morning.
Then you realize, she was pretty easy for a Fabswinger, so how many people has she slept with, how clean is she and she didn't have a condom. so your cock will turn black and fall off next week.
Nah sorry it takes less time, less money, is safer and you get a girl who knows what to do for about the same overall price. Only worth it if you like the chase and if thats your can, I suggest you take up fox hunting.
