Sex is the glue of relationships, Caitlin, and it's what life is all about. It's the opposite of death, of giving up, of getting swamped by... What's out there. See it as symbolic.

Tell me about love when you've been with someone for years, cared for them when they're ill, put up with them when they're miserable or grumpy, taken the sharp side of their tongue and still come back. Tell me about love when you've acted quite appallingly, and the other person has still accepted you.
