And I know this is nit-picky but some of your advice is just plain wrong.

The penis is mostly cartilage. Like the fleshy part of your ears. Bodybuilding grows muscle mass and lowers bodyfat. The dick is neither. So just as a bodybuilder's ears don't change, neither does his dick. Similarly, if you go on a Haagen-Dazs binge and gain 200lbs, you'll find that neither your ears or dick gain any weight. It's not a place on the body that has either muscle or bodyfat.
A penis contains no cartilage.
