This whole idea of "virtualizing" and "democratizing" (read; corporatizing and monetizing) what is already probably the most intense physical and interpersonal experience you can already have; an experience that's not only freely available, but literally at your fingertips, at any time (or not even that: you just need to close your eyes, and think of... entertaining thoughts) -- is profoundly, profoundly depressing.
And besides, with all these must, dead-trees 17th- 20th century smut novels to read -- who can possibly find the time?
Forget this online stuff. Get out of your apartment, and find a real, actual person to talk to. I know it can seem hard, sometimes. But really, is isn't.
