been there, done that...
The term "swinger" is a little outdated. It conjures images of senior-citizen wife-swapping, but anyone who is using adultfriendfinder or xpeeps or sites like those to hook up for sex is a swinger. Those sites are about 98% desperate single guys, but with a good photo it is still possible to meet people. It also helps to be in an urban area with a lot of people. If you're a single guy who wants to get laid in the swinging community, you can't be all that picky or uptight. I had my best 'relationships' with older women who had even older husbands whose sexual prowess had declined with age but would let their wives have fun with other guys, in exchange for being able to watch and take pictures. I'm probably still part of a few amateur porn collections
But all of that was in my early 20's, and I have no interest in hanging with the sex freaks anymore. All of us on this site have access to the information to build the necessary skills to get a choice gf and have great sex, maybe even an occasional threesome with a woman of her liking. When you have all of that going on for you, then the people with ads on the swinging sites start to look sad and desperate.
