Sorry, I just felt I had to answer this, because it hits me really personally. It is NOT bad to j/o and think about things! The Bible says NOTHING about it anywhere, so any Christian who says it's a sin has no evidence to say so. Trust me, almost every boy and man does it, so don't worry about it. I only met one guy who said he never did it in his life, and I don't think anyone believed him, lol!

Take it easy,
