A 1982 official statement by the church’s First Presidency — which makes it official church doctrine. One of the signatories was Mitt’s cousin, Marion G. Romney:
Married persons should understand that if in their marital relations they are guilty of unnatural, impure, or unholy practices, they should not enter the temple unless and until they repent and discontinue any such practices. Husbands and wives who are aware of these requirements can determine by themselves their standing before the Lord. All of this should be conveyed without having priesthood leaders focus upon intimate matters which are a part of husband and wife relationships. Skillful interviewing and counseling can occur without discussion of clinical details by placing firm responsibility on individual members of the Church to put their lives in order before exercising the privilege of entering a house of the Lord. The First Presidency has interpreted oral sex as constituting an unnatural, impure, or unholy practice.

That’s good ol’ Mitt, a head for business, but nothing else.
