Get in shape and shave your pubic hair. Those are the only sure-fire things you can do to maximize your wanger. There is nothing to do to get size. Maybe someday there will be "Penis Implants," but until that day arrives..just get in shape and shave your pubes.
Drink pineapple or guava juice to "sweeten up" your loads. Though I have no proof other than a "gut instinct," I actually think drinking milk helps "thicken up the load" too. Drink a glass a day for a week, don't wank for 2 days, then wank and see what you think....
