And the only rule is that there are no rules!

“

By waiting and waiting and waiting to commit to someone, our capacity for love shrinks and withers. This doesn't mean that women or men should marry the first reasonable person to come along, or someone with whom they are not in love. But we should, at a much earlier age than we do now, take a serious attitude toward dating and begin preparing ourselves to settle down. For it's in the act of taking up the roles we've been taught to avoid or postpone––wife, husband, mother, father––that we build our identities, expand our lives, and achieve the fullness of character we desire. -- Danielle Crittenden, 1999

Teenagers and college-aged students tend to avoid the more formal activity of dating, and prefer casual no-strings-attached experiments sometimes described as hookups. It permits young women to "go out and fit into the social scene, get attention from young men, and learn about sexuality", according to one report by sociologists. The term hookup can describe a wide variety of behavior ranging from kissing to non-genital touching to make-out sessions; according to one report, only about one third of people had sexual intercourse.
