Is it normal to get off for 5+ hours?

Like you, I like to fap. But when I do, I do it for hours without food, bathroom breaks, or cumming in between. The longest I think I went for was close to twelve hours one time. (What keeps me going is the limitless amount of material on the intrawebz).

If I try to get off for five minutes or something pathetic like that, it doesn't do much for me anymore. I that normal?
