Well, having a penis only makes you a male, not a man.
Being a man means you do stuff that belongs in mantages, like cutting down trees, building houses out of those trees, growing a beard, and owning some kind of primitive double barrel shotgun. Lots of focus on the beard though. But in order to be a man, you have to either a.) live on a mountain, b.) work on a ranch/ farm, c.)be in the military or, d.) be a cowboy/ where a hat and jeans (basically, you have to dress presentable but tough, not like the douchebags these days with tight pants and mascara. Emo hair is only acceptable if you have a nice beard to go along with it and you look rugged).
Jacking off is more of a "guy" thing.
I sometimes have moments where I qualify as a man, but am still on the way.
