The Protein Man

A man of mythical sexual prowess. Not only known for his monstrous size sexual appendage but also for his non-stop, sexual climaxes without any refractory period. He is always up to the task and brothels fear him for his marathon sex sessions which end up leaving all the working girls out of comission for days on end. You'll usually find him in Japanese hentai anime recaps on Youtube.

Chuck: I can go all night, non-stop, fucking the brains out of the sluttiest of bitches. I'm the protein man.
Jason: Didn't I tell ya to lay off that meth?

Man protein

The body fluid that ejects from the penis.

I suck his dick every morning for my daily intake of man protein.
