i thought the 83 article was the one that stated what goes on in the marital bed is no ones business?
It says both:
As already stated, it is not for elders to "police" the private marital matters of couples in the congregation. However, if it becomes known that a member of the congregation is practicing or openly advocating perverted sex relations within the marriage bond, that one certainly would not be irreprehensible, and so would not be acceptable for special privileges, such as serving as an elder, a ministerial servant or a pioneer. Such practice and advocacy could even lead to expulsion from the congregation.
