Okay, I'm looking at the 1991 Edition of Pay Attention to Yourselves and All the Flock, pages 92-94
Sexual misconduct, including adultery, fornication, and other forms of "por.nei'a."
Uncleanness includes an intentional momentary touching of sexual parts or caressing of breasts. (1 Thess. 4:7, 8; 1 Tim. 5 :1, 2) Such minor uncleanness can be handled at the discretion of an elder or two; it does not require a judicial hearing. There is a need for strong counsel, admonition, and assistance to help the individual to maintain chaste conduct in the future. If not corrected, such conduct may escalate in gravity and by frequent repetition become loose conduct.
Loose conduct is a shocking, flagrant disregard for Jehovah's moral standards. (Gal. 5:19; w83 3/15 p. 31; w73 9/15 pp. 574-6) It may include the willful practice of heavy petting or the fondling of breasts. The nature, circumstances, and actual extent of what has occurred may indicate loose conduct, which would require judicial action.
Such practices can easily lead to por.nei'a . "Por.nei'a" involves immoral use of the genitals of at least one human (whether in a natural or a perverted way), and there must have been another party to the immorality - a human of either sex or a beast; willing participation incurs guilt and requires judicial action . It is not a casual touching of the sex organs between persons but involves the manipulation of the genitals. (w83 6/1 pp. 23-6 ; w83 3/15 pp. 30-1) It includes oral and anal sex or mutual masturbation between persons not married to each other, homosexuality, lesbianism, fornication, adultery, incest, and bestiality. (Lev. 20:10, 13, 15, 16 ; Rom. 1:24, 26, 27, 32; 1 Cor. 6:9, 10)
Also included are sexual abuse of children, including practices involving a catamite (a boy kept for purposes of sexual perversion). (Deut . 23:17, 18, Ref. Bi., ftns.)
Victims of sexual abuse need to be treated with extreme thoughtfulness and kindness . Elders should always do what they reasonably can to protect children from further abuse ; follow the Society's directives on such matters. (g85 1/22 p. 8)
Self-abuse, or masturbation, is not "por.nei'a," nor would one who was raped be guilty of por.nei'a. (w83 3/15 p. 30; w74 3/1 p. 160; it-1 pp. 862-4 ; tp p. 144) The term por.nei'a lays emphasis on both the lewd nature and the intent of the person's conduct, and it embraces all illicit sexual activity characteristic of that found in a house of prostitution.
Copulation (as in penetration) is not necessary to constitute por.nei'a, and neither is sexual climax.
In borderline cases, it is the responsibility of the judicial committee to weigh carefully the Scriptures and the particular facts in the case to determine whether por.nei'a was involved. This responsibility should not be taken lightly, especially when Scriptural freedom to remarry is involved. (Mal . 2:16a )
