For people who are desperate and searching, sexuality on the Internet offers an incredible release.

You're married to a woman who has no objection to another woman joining the couple. Then she brings in her boyfriend. Suddenly you realize - my God! - you can love more than one person. In fact, you can love several people at the same time.

We are all potential murderers, and we are all potential rapists and abusers.
