Zane: When flacid, your penis is pretty compact. to get erect, your body redirects blood to your penis, making it swell. But you were erect for so long that your body generated new blood. Now you can't go flacid because you're "full". This became your new "baseline" state, and now you're getting errections on top of this size. This cycle repeats, making your penis grow over time. I estimate your current erection to be about fifty-two inches.
