All men I had dealt with behaved that way. Although I'm American, so my sampling is non-representative - North American dudes are well known to be pussy pounding whores.
Men love sex because they are biologically intended to fuck lots of bitches and get them preggers. They're intended to be sperm delivery machines and std-spreaders.
I.e. men are lowly animals, unable to control their instincts.
No, you misunderstand. Being horny does not imply being unable to control instincts. Men can control their instincts, but they have to be trained to do so by their bitch. A man's women is pretty much his acquired pussy administrator, and so is responsible for the way the man fucks.
