The fact is that our intellects can tell us all sorts of things, many of which are perfectly reasonable & make lots of sense, but our FEELINGS don't always cooperate! I'd venture to say that for most of us, when we find someone we really, really, REALLY love in a romantic sense of the word, it's the extremely rare person who can contentedly "share" them with another person sexually, regardless of HOW much hugging goes on amongst the larger group!

Just basing this on my own personal observations, of course.
