eroticism

But sex is not just which part of whose body was where. It’s the relationship between the participants, the furniture in the room, or the leaves on the tree, what gets said before and after, the emotions—act of love, act of lust, act of hate, act of indifference, act of violence, act of despair, act of manipulation, act of hope. Those things have to be part of it.
