The inappropriate (mothers and fathers)

The inappropriate (mothers and fathers) What is their concentration?

I see parents in the park with their children. The fathers and mothers (or shall I just write men and women?); fathers in one area, mothers in another. Collective segregating..momentary but subconscious or not?
How much do they interact, if they do indeed interact? How is this seen from their perspectives?
What IS the idea of mother and father, when one actually becomes one? How does this get acted out for each individual trying to do the best…their best for them? The children?
What interests me more is the idea of attraction between/among mothers/fathers of different children. Is the erotic still there for many? How is erotic love seen and acted out? How does the child come or not come between adults and pleasure? How is desire for egoistic exhibition or lust hindered, encouraged, aggravated or deadened?
These boundaries are not so strong in my mind. Surely, they cannot be. Love for a child or love for a woman or man or erotic love for the friend or lust for the stranger… are there not elements of all of these feelings within each other? Can they possibly function together? (All the questions are for me or rhetorical.)
