I home teach a person who asked me this question.
I can remember when I was serving in the Bishopric and during a youth interview the young lady I was interviewing started to tell me about a situation she was in. I quickly stopped her, told her I wasn’t the one to talk to. Since it was a sin of morality I told her to talk to the Bishop.
But where is the line drawn?
Is it morality only? Which morality sins? Is it lust, or Playboy centerfolds, or po#n, or petting, or or or? Is there something in the handbook that tells us?
Then that brings up another question. If the Bishop needs to be involved with our forgiveness process for “big” sins, then why not little ones too? Why does he have to be involved?
I told the person I’d get some answers and get back to the person. So give me some answers.
