"Do the church and the school see masturbation as a sin?

"Well, it is interesting. I would frame it this way. Masturbation is a behavior that, if continued, could over time lead to things that are sinful, so the counsel that the church gives to its leaders is to counsel with young people to help them understand that their bodies are the temple of the Holy Ghost. That comes right out of Corinthians, that is what Paul taught, and it is a beautiful doctrine—that our bodies are a great gift from God and we need to take good care of them, and that the procreative powers that God has given us, he cares very much about how they are used, and so that we need to learn to use them in ways that are in accordance with his will and his mind."

He only says it could lead things that are sinful. Is the church
emphasizing this issue a lot less than in the past?

What an imbacile. He should read Corinthians with a good Christian commentary and Greek lexicon if he really wants to understand the text (true or not). Not only do the Mormons take the Bible out of context, but those sections that contradict their own made up theology, 'were not translated correctly'. Can you imagine 70+ scholars, using a stone in hat, translating the Torah and Prophets into the Septaugint?

I hope the biology department just laughed.

I know a councilor on BYU-I campus and they have several group therapy classes for men that masturbate.

A normal activity becomes abnormal in Mormonism, and needs therapy. That is a big cause of suicide because these guys try to overcome the normal urges and then are humiliated and think they are doomed to hell when they "mess up".

Man, they guys in that video were making seriously gay eyes at each other. It couldn't have been more homoerotic if it tried. I think they need to make another video about the dangers of getting gay with roomates. Set against the backdrop of wartorn Europe, of course.
