We've met many many people of all shapes and sizes, none of us are perfect, and those that think they are, usually (In our experience) are crap in bed anyway lol, but your missing the point, which is, we as Swingers are all after 1 thing, more sex, interesting sex, different sex, exciting sex, threesums, foursomes, even moresums, but sex.
As couples, we are not seeking love, or affection, as we have that with our current partners, and accordingly, its more than a visual image that makes for great sex, and memorable meets, its personality, wit, humour, and confidence, friendship and many other points too, but personal body shame should never enter into the equation.
You've already made the biggest decision ever in your adult sexual lives, to share yourself with other people, so your confidence is there, use it and enjoy, but never worry about your body, because as swingers, we are looking for a lot more than body image xxxx
