I'll put this to you in simple, straightforward terms: According to the First Presidency's real view, any husband and wife who engage in oral sex are unworthy to enter the temple. But they have retracted that publicly, because of the member backlash that they have no right to judge what happens in marital bedrooms.
You've already admitted that "Bishops like yourself" never made the letter public in any great numbers, so its no wonder that the "backlash" is a figment of your imagination (which is probably why, in some 26 years since it was circulated, neither I nor anybody I know in the Church have ever heard of such a backlash or participated in it).
This was the "interpretation" of the First Presidency of the time. You've already admitted it was not doctrine and, as such, was not binding upon the general membership of the Church.
A tortured conscience needs this kind of fodder doesn't it Ray?
Next: licked cupcakes...
So it's not a case of "thus saith the Lord", but accommodation. Sort of like trying to decide whether it's Mesoamerica, New York, or bust. The prevailing scholarly views have, apparently, as much weight as "revelation".
Is there a prevailing scholarly view of oral sex?
