Have you ever been in a threesome? What year was it? If not would you do one now as seniors?

We have been together 45 years. We both have what I would consider low body counts. Of course that number is subjective. We are not in a Lifestyle couple but have had quite a few threesomes over the decades. Mainly involved three different friends that joined us on occasion. It has always been fun and drama free.
Does it seem like when we were younger this was a much rarer thing than it is with today’s youth or at least it feels that way. I think Mainly because the young women of my time seemed a bit more conservative than young women today. Maybe I’m wrong. Now that we started our hobby 2 years ago we get constant offers, mainly from women younger than 35. But men of all ages. We don’t accept because we prefer a friendship with it.
