First, there was phone sex, and that was kind of sad.
Next, there was cybersex, and that was even sadder, because it subtracts the human voice from the equation, and adds spam, 14-year-old boys, and people who lie about their gender.
Now, there's SMS sex, advertised on late night television. It's like cybersex, but with a smaller screen. And you can take it anywhere, even on the bus.
I ride the bus. World, please stop inventing things.
