The first time that any approval of a non-abstinence fertility control method was publicly expressed occurred in a 1942 Improvement Era article in which Apostle John Widtsoe mentioned the rhythm method as an acceptable means of spacing children.
In 1969 the first and only First Presidency statement on birth control was released reemphasizing that it was "contrary to the teachings of the Church artificially to curtail or prevent the birth of children", though, for the first time there was a clarification that men should be considerate to "conserve" the "health and strength" of their wives when planning families since they carry the "greater responsibility" for bearing and rearing children.
The oral sex ban, however, was neither removed, modified, or clarified as the only additional directive to leaders was that "if the member has enough anxiety about the propriety of the conduct to ask about it, the best course would be to discontinue it".
Subsequent discussion of marital sex warned against behaviors that the church considered unnatural, impure, and unholy including Spencer Condie's warning that when couples "participate in unholy practices" during their physical intimacy it can become a "disruptive force" in their marriage.
However, in teaching children about sexual morals and birth control, Mormons parents have ranked among the lowest in comfort discussing these topics with their children among US parents of all religious affiliations.
In discussing another method of family planning the church "strongly discourages" surgical sterilization like vasectomies and tubal ligation and only allows it for serious medical conditions after discussing it with a bishop.
Sexuality has a prominent role within the theology of Mormonism.
The Church of Jesus Christ of Latter-day Saints (LDS Church) teaches that gender is defined in the premortal existence, and that part of the purpose of mortal life is for men and women to be sealed together, forming bonds that allow them to progress eternally together in the afterlife.
The church is sensitive about its historical relationship with polygamy, and entry into a polygamous marriage, even where legal, will result in mandatory consideration of church discipline and possible excommunication.
Since 1985 the church has provided a manual for parents to use in discussing sexuality with their children.
The manual includes statements that "prophets have condemned [masturbation] as a sin" and "perversion of the body's passions" that causes one to "become carnal".
