Are you committing to lust in your heart? Are you committing adultery with a married woman in your heart? Are you engaging in degenerate fantasies of fornication in your heart? We don't have to argue the finer details of theology here. On this, you can tell better than any of us if what you are doing is pleasing to God. If you believe yourself to be sinning, repent and work to do right. Repentance isn't just about following the rules. It's about letting go of that which weakens us, and getting closer to God.
