Not to sound too complicated, but it's all so very personal, fluid and changing and expanding. Life's funny that way.
I have been in several V's over the years, almost 20 years as a hinge. Close V's sometimes groups of us together, loving, playing. Sometimes they almost turning into triads, but still not quite. One of us (me) knowing that is not quite what I wanted. Sometimes V's can appear to be groups of triads or groups of close quads.but still V's.
