my 2 cents is it cannot work for an extended period of time.my wife and i 'played' mostly mfm for about 3 years until she tired of it. after resentful nagging on my part, she eventually set up a friend w me, and from my experience i think open dating opens the door for wonderful sex, which leads to someone doing more and all they can to please you which leads to feelings of more than sex for sex. in my case i was ready to leave for who knows whatever reason. but maybe thats just our case i also know couples in our area that have split over the same issue. seems that playing together is ok, but apart invites trouble. besides as pretty as you are, its just a matter of time and poof, you are gone. suprise me in a year and tell me i am wrong, but my money is on catastrophy...
