It's nearly Valentine's Day and we're being blitzed with images of couples smooching so I was suddenly reminded of that scene from Pretty Woman. Julia Roberts' character was a prostitute who didn't kiss her johns on the mouth because for her, kissing was intimate but sex was not.
What happens when there is instant intense sexual chemistry between two people? Sometimes it's just physical attraction. Sometimes there is deeper meaning that can explain why some relationships that begin like this end disastrously while others thrive.
