Some people don't have sex 'til they're married. Some people elect to maintain professions which declare that sex is truly meaningless (stripper, escort, etc.). Yet, the majority of the world is probably somewhere in between. A lot of women would be apalled if a handsome man came up to them in a restaurant and proposed intercourse. But, if she was set up with that man on a blind date at the same restaurant, suddenly sex that evening could become a proposition. How can sacred and meaningless be a first name basis away?
