NONE.
All of this really is a personal choice.
Based on the assumption of the word or moral act of "fidelity".
I have been on both sides of the fence, therefore I know where I sit........or would like to.
I also am adaptable, sometimes begrudgingly.
I know I don't like drama, and I do like the word "trust".
To some degree, everyone makes their own way in life.
Most men fit into new categories as the culture and times change, as do women.
