Threesome's when dating and in relationships over 50

My workmate of the last two days (another guy) shocked me yesterday by telling me he got offered and accepted the offer of having a threesome when he was 50 (he's early 60's now). With two women (both of whom he knows).

I've never had one. I don't really know any women in any sort of close social kind of way.

So for some people dreams do come true!
