Interesting, Sharon... so a difference between social exclusivity/advancement of a relationship, and just plain intimacy. It makes sense, in a way.
I wonder, though, why so many people get frustrated with "sexless" marriages, even if they do lots of cuddling and kissing. If they are getting their "intimacy" kicks from kissing, then who needs sex?
(Well, I do, but I find kissing and sex to be just as intimate!)
