"I am only doing this to raise a specific amount of money and then I will quit."

The e-mail came from a college student named Tera who said she needed money to stay in school and pursue her degree in biotechnology. She was therefore selling nude videos of herself. Boy, did she get a wrong e-mail address. As a gay guy, I'm not much of a potential customer. The volume of sex-related e-mails I received was second only to those promising riches. Several offered pornography, but there also were products including a "sexually stimulating fragrance oil" described as a human pheromone. Coleman didn't think much of it. "This came from a craze a few years ago when it was found that insect pheromones might play a role in attraction. But insects have a completely different physiology than humans. There is no evidence this works in human beings, unfortunately."
