Point well taken...
I just would hate for something to happen that neither one of you can take back.
With the exception of his first wife (that he married right out of the service) I am the first NON-swinging wife my Old Grump has married. I had also dabbled a bit in all kinda adult activities as a single woman after my divorce from my first husband so I know that this was *meh* at best for me and NOT preferential for a longterm committed situation. But that is ME and I don't judge. I was merely advising you on the experiences that my Old Grump had had for 20+ years while cautioning others AGAINST swinging.
After 36 years though I am thinkin that the two of you are beyond grown and know yourselves and one another well enough to partake if you so choose.
Better still, I will ask my Old Grump to take a look and see what advice he can offer you. To this day my Old Grump and I get approached constantly, matter of fact, used to creep me out because I wasn't looking for any sort of threesome situation, yet there it was ALL THE TIME.
Now I realize that it is just that the two of us are so much fun and are so laid back that these women just want to *capture a bit of the magic* we have. But sorry... I am too possessive over that magic. Maybe one day I will change that, but I don't see that happening any time soon.
I know there are several members of couples who do swing on elite, though they don't always post up frequently... which is a shame really. Lotta people could benefit from the healthy exchanges about human sexuality.
