This promise falls under the law of chastity.
Chastity is sexual purity. Those who are chaste are morally clean in their thoughts, words, and actions. Chastity means not having any sexual relations before marriage. It also means complete fidelity to husband or wife during marriage.LDS Student Manual, “Chastity”
Sexual purity is very important. We’ve been given a physical body in the image of our Heavenly Father and have been told to keep it sacred.
So …why is sex okay for Mormons?
[Because] [p]hysical intimacy between husband and wife is beautiful and sacred. It is ordained of God for the creation of children and for the expression of love within marriage.LDS Student Manual, “Chastity”
…Sometimes people try to convince themselves that sexual relations outside of marriage are acceptable if the participants love one another. This is not true. Breaking the law of chastity and encouraging someone else to do so is not an expression of love. People who love each other will never endanger one another’s happiness and safety in exchange for temporary personal pleasure.
When people care for one another enough to keep the law of chastity, their love, trust, and commitment increase, resulting in greater happiness and unity. In contrast, relationships built on sexual immorality sour quickly. Those who engage in sexual immorality often feel fear, guilt, and shame. Bitterness, jealousy, and hatred soon replace any positive feelings that once existed in their relationship.
Breaking the law of chastity happens. Since it’s a serious sin, one must talk to his or her bishop as part of the repentance process. Depending on the severity of the sin, the errant member may also need to attend a court; the court may then decide to disfellowship or excommunicate the member.
Don’t worry -a former member of the LDS church may reapply for membership after repentance and the recommendation of his or her bishop.

We Mormons are officially members of The Church of Jesus Christ of Latter-day Saints and are to drop any name but that. Since many recognize the nickname of ‘Mormon’ and it works with the alliteration so well, however, I will use the term.
My other note is that I will keep to official doctrinal practices. I will add my own application of them, especially in response to comments.
My final note is that I LOVE discussing anything I write. Don’t be rude, obviously, but any and all queries or responses are welcome.
My final note beyond the final note is that I do not seek to convert anyone. I ought to, but am motivated by forming connections, answering curiosity, and straightening pictures. So, you’re safe.
