"No expectations or as few as you can live with" I say. Having boundaries is valid though. It gives a sense of directuon but not forced direction.
To me boundaries are fluid, as upposed to rules, which are fixed. You can make it a rule to always practice safe sex as you both understand it together for instance. A boundary would be that you would like to look for women right now and see how that goes. It give some breathing room that the women you might meet be friends with you instead of lovers or only work for one of you or that you might meet a man in the mean time. In this way there is repect for the natural flow of things; all doors are visible, its a choice to open them.
Anyone want to be friends on Facebook?
