The booklet—recently circulated through a Web site for pedophiles—had been written, it said, "for any boy who is old enough to be able to read it."

Called "Straight Talk for Boys," it is an 18-page discussion of sex, particularly between children and adults, from the pedophiles' viewpoint. Such encounters are depicted as harmless, even beneficial. The document criticizes parents and therapists. And it encourages boys to wear Speedo bathing suits and shower naked in public places.

But it repeatedly returns to one message: boys should never tell about sex with adults. "Older boys and men may be frightened about getting caught having sex play with you, because they can be put in jail," it says. "So you have to think of ways to 'signal' your interest in another person without openly saying what you want," adding that "nobody else can know about what you agree to do."

The booklet comes with instructions, advising pedophiles on how to distribute it. "The best and safest way is to leave quantities of the booklet in places where boys in the 8 to 14 range can find them, and where adults will not discover them too quickly," the instructions read. "Obviously, you don't want to be observed placing the booklets in your chosen locations."

The booklet reflects how pedophiles can use the Internet to advance their interests in the real world. Like many of those efforts, this one involved deception: the booklet does not reveal, for example, that it has been written and distributed by men who are sexually attracted to children, but instead portrays itself as objective fact.

Using deception to gain access to children is a recurring theme. For example, on a site for adults attracted to boys, someone calling himself Vespucci asked in June whether a single man could become a foster father. The respondents cautioned Vespucci to disguise his pedophilia.

"You better have a darned good excuse why you never married, such as your fiancße died in a car wreck," replied a man calling himself simply "d." "I highly recommend you date women for several years and keep at least a couple of those relationships going for at least a couple of months. Around the women, make a point of being nice to children."

The deception would be worthwhile, d wrote. "It will help out in the reference-check dept. when you apply."
