1st post - saw Michele on Fox. Google turned up this site. I have been browsing around here for about a week or so and decided to join. The new book doesn't apply to me, but found a copy of SSM in paperback that I just started. I hope it will help.
I am HD, my wife is LD, at least in our M. No affair that I can tell, but she talks (and emails) a friend about doing it with various celebs often enough for me to ask here about it. If we did it as often as W talked about it with movie stars, I'd be the envy of a lot of other men. For us, its anywhere from 2-4 times a month. Every now and then she initiates. In all cases, everyone is satisfied. (One clue on this front is how ticked off W gets the few times there have been interruptions. Once the engine is started, she insists we finish the race.)
So, is this something to worry about? Do other women do this sort of thing? (And why!!) If the concensus of women here feel this is just "women acting like men in a locker room", I can live with it. If not, I'm open to any advice.
