The timing has to be right for everyone involved. My wife and I have done this twice. Once M/M/F and once F/F/M. Both ways were great...better for me the F/F way, but she had as much pleasure with both of them. And I had the luck of a 5 way on Senior class trip to DC, F/F/M/M/M. THAT was a good time. I'd do it again though at the drop of a hat...any hat.
