Actually, I just recently ran across a totally nude picture of my wife on a site. It was taken by me about 50 years ago when we were both around 18 yo. Though we never posted any pictures on-line we did swap pictures with other couples we corresponded with looking for couples to wife-swap with hoping they would be discreet. I must admit I was very surprised to see the picture, but also turned on. Back then my wife was an avid exhibitionist, but when the internet got going we were worried about the wrong people seeing any pictures of her since her interest in being in that kind of lifestyle had changed and she'd came from a religious family. But still never regreted our 20 years in the swinger lifestyle.
