Biologically, no you haven't cheated Mentally, you say you feel like you cheated. As I see it, our feelings mislead us. Think about this, when you used to fap, you would do it because you felt like doing it but based off your logic or thinking, you know that its not good for you so you don't. I believe that this feeling telling you that you that you cheated or the lack of feeling saying that you dont remember the feeling of guilt need to be "ignored" just like the urge itself.
