As a matter of definition, the term mLTR stands for Multiple Long Term Relationships, and it refers to a situation where you have several women as LTR’s and each of them knows you are seeing other women. They are OK with it either because the situation caters to some vicarious bisexuality on the part of the women, or because they see you as enough of a prize that they are willing to go along with the arrangement just to be with you.
