Even Brigham Young didn't want to hear about your masturbation!

“When we ask the brethren, as we frequently do, to speak in sacrament meetings, we wish them, if they have injured their neighbors, to confess their wrongs; but do not tell about your nonsensical conduct that nobody knows of but yourselves. Tell to the public that which belongs to the public. If you have sinned against the people, confess to them. If you have sinned against a family or a neighborhood, go to them and confess. If you have sinned against your Ward, confess to your Ward. If you have sinned against one individual, take that person by yourselves and make your confession to him. And if you have sinned against your God, or against yourselves, confess to God, and keep the matter to yourselves, for I do not want to know anything about it” (Discourses of Brigham Young, sel. John A. Widtsoe [1954], 158).
