What does it mean to be “one flesh”?
-- Here's a few questions to get into specifics:
Does 'one flesh' happen when you get married?
Does it happen with sex? Does first base count? Second? Third?
Is it a continuing process that builds slowly or is it more of an on-off status that happens at a moment in time?
Is it undoable?
Is it possible to be one flesh with many partners?
-- What are some interesting reads? I'm looking for both reliable and otherwise.
