If Steve's primary love strategy wasn't physical affection, there would be no polyamory, right?
Erin's intimate relationships with other people are not physically intimate, but she is such an amazingly compassionate soul that her relationships are bound to be very deep and truly loving....without any polyamory whatsoever.
So it seems like intimacy is a path everyone chooses according to their heart's desire.
But I wonder why did Steve's heart have to desire a path like polyamory? Couldn't it be more of soul-based love like Erin's?
I guess on this earthly life, when you are in a human male body, it works this way for Steve.
