I’m in the same boat as you my friend. Idle hands are the devils playground after all. It seems whenever people leave the house and I’m aware of being “alone” that I am bombarded with lust and sinful temptations. And I am ashamed to admit that nine times in ten, the sin wins out. I don’t know if that’s how it is for you, habitual, or if there is a deeper rooted problem? I have yet to find something to do to conquer it, but I believe if I were to find something to occupy my time with, exert that extra energy in a constructive way, than I would not feel as inclined to act on sinful urges. Personally, I’m thinking about taking up a few musical instruments. Not everyone has the patience or desire to do that, but I would suggest a hobby? Something that you enjoy that would occupy your mind fully to focus on the task at hand. Then sin has no place for you. Just stay busy!
