I used to struggle with masturbation/pornography, but have since made major changes in my life and repented. I have been clean for three months now, and I am about to have my pre-mission interview next week. I feel like I have been forgiven by the Lord through my personal prayers, but do I still need to address this with my Bishop? If so, is it likely that he will delay my mission papers? For how long?
