My wife and I are very open, although my wife is very self concious but loves cfnm, I've taken on a clothed female naked male lifestyle as my wife loves it and I enjoy seeing her happy and I now can wank in front of her whereever I want without feeling embarrassed about it!
We have recently started going to a nudist beach near our house, my wife stays in swimmers when we go and I strip off. Sometimes we get a spot in the dunes so after a swim and a bit of looking at the naked people I feel the need for a wank. My wife loves this and will lay there watching me jack off on the beach, some people walking by do look and some have stopped and watched!
Some of the regular nudists have come and talked to us and welcomed us, a couple have mentioned how they have noticed me having a wank sometimes and that at certain times some of the guys get together for a circle jerk up in the dunes if I'm interested.
I've yet to attend but my wife is really encouraging me to go and she's very excited to watch, apparently some of the guys wives also come to watch, so this weekend will be the first time. If I enjoy it I may continue, my wife is sure keen. I will update after this weekend how it goes.
