We are late 60's and have been active in the lifestyle for well over 35 years.
I was the only guy my wife had been with, we started dating just before our 18th birthdays, she was a sweet ever so innocent church going Catholic girl who never touches alcohol (still never does), she was so naïve that she thought every time a woman had sex she had a baby and that her mother must have been a very sexy woman as she had six children (the Catholic church has a lot to answer for) I had to buy sex education book to educate her to the facts of sexuality, it finally paid off as I took her cherry when we turned 19.
We married at 21, had our family at 28 and 30 and she had her tubes tied after our second child “her decision”. Without going into a long story we joined a nudist club when we were early 30’s and soon found out their was an underground swinging group at the nudist club, we talked about it, “we found out that some of the people we had became friends with were swingers” I kept trying to steer her in the direction of swinging and when we were 35 and married 15 years she went with her first ever other guy, that opened the doors to swinging, swapping, M F M threesomes and her being a hot wife with other guys to us, “and she took to the lifestyle like a duck to water”, in fact at times I started to wonder just how big a Pandora’s box I had opened, she had me biting my tongue at times with some of the things she got up to!
We are now late 60’s, married 48 years and she is still a player, it’s been a pretty good life I can tell you.
PS She still never touches alcohol “a lot of women use alcohol as an excuse to explain what they get up to, not my wife, I tell her everything she has done she has done “stone cold sober out of pure lust”.
