When we were first married, I hinted to my wife that I would like to do a three way. She never seemed too keen on the idea. Then, she began to feminize me. I was a bit surprised then when she told me that she'd been thinking of my suggestion to have a three way, and that she'd decided it would be fun.
However, this isn't exactly what I had in mind when I'd suggested it. My wife, on the other hand, was looking forward to it.
