Interesting that you've had such a long marriage and been able to explore on the side too, was she supportive of that or did you keep it on the down-low? Did she participate with you or was it something you enjoyed doing on your own?
We've utilized a clothing optional campground countless times during the past 20 years, because I enjoy nude sunbathing. She refuses to be bare in public, but enjoys observing the naturalist freedoms others experience. During the past ten years the campground's general population has evolved into a 9:1 male/female ratio. She permits me to visit and camp alone there around six times each summer. I would speculate she knows my desires to expose my erections, and suspects that I jerk-off with guys. We've only discussed my female encounters while I've camped alone, though.
