Many of us here have taken issue with a lot of the comments by Pegg (a Jehovah's Wittness). Looking into the religion's attitude toward masturbation I came across the following comments in the religion's official publications.
Masturbation
Jehovah's Witnesses are not to masturbate on the grounds that it is "unclean", displays "greediness", leads to sexual promiscuity and even homosexuality. Masturbation is not in itself a disfellowshipping sin, but can be a reason for a person to be withheld privileges.
Watchtower May 15 1970, p.315 Avoiding the Snare of Homosexuality
Helpful in this regard, then, is appreciating the fact that autoeroticism or masturbation is no mere innocent pastime but rather a practice that can lead to homosexual acts. How so? In that self-induced masturbation may make it easier and more tempting for one to engage in mutual masturbation, which is a form of homosexuality. Sincerely striving against this practice will go far to protect a youth

Watchtower 1976 Feb 15 pp.122-3
Likewise, unclean practices, such as masturbation, which can be a steppingstone to homosexuality, have been dealt with in a serious, yet understanding, way, to help individuals keep clean and pure in Jehovah's eyes.

Watchtower 1973 Sep 15 pp.564-5 Breaking Free of Self-Abuse-Why? How?
Because masturbation is unnatural. Granted, small children have little concept of the sexual relationship of male and female. But with adolescence comes an inner awareness that tells the male his satisfaction of sexual desire is to be found in the female, and vice versa. Masturbation (like homosexuality) ignores or bypasses that natural arrangement. It is one form of leaving "the natural use of the female" for "one contrary to nature."
Because the practice is one "contrary to nature," the masturbator pays a mental penalty. The habitual practice cripples his social and emotional development, hinders his attaining a healthful outlook and attitude toward the other sex and toward people in general. It can 'turn the person inward' upon himself, making him introverted. Or it can, and frequently does, lead into homosexuality,

Your Youth (1976) p.39 Chapter 5 Masturbation and Homosexuality
Weakly giving in to sexual desires by masturbation will certainly not give you strength when faced with a situation tempting you to commit fornication-or even homosexuality. Just the opposite, it cultivates wrong thinking and wrong desire. In fact, masturbation can lead into homosexuality.

As we have seen, masturbation is indeed a "hurtful desire." It is also "uncleanness," for it is an immoral practice, and this explains why the masturbator generally is ashamed of himself and hides his repugnant act from the sight of others..

Other than it's archaic and misguided outlook on the physiology of masturbation I found its repeated insistence that it can easily lead to homosexuality almost criminal. Getting the facts wrong is one thing, but fabricating consequences is outright lying. The JW organization should be ashamed of itself.
