Women are more commitment- and family-oriented than men. In fact, I’d argue that innate wiring is precisely one of the greatest things that draws them to this relationship.
I’ve heard multiple ANR women stress the importance of finding the right man, to whom they enjoy unrestricted access, prior to bringing in the milk, because of the great deal of commitment required to induce and maintain the milk flow.
The deep, sacred bond of togetherness and intimacy is the pull factor for all Couples Nursers, more so for women.
