1) They can ejaculate while limp
While boners and ejaculation are usually a package deal, men don’t actually have to be hard to expel semen, shows a study from California’s Oakland Medical Center. A man’s pelvic muscles contract when he ejaculates, but those muscles aren’t directly tied to the processes that make his penis erect. So while unusual, a man can squeeze some out even when he’s flaccid, the study authors say.

2)They can ejaculate semen up to 8feet
That’s according to a study conducted years ago at the University of Indiana by the famous sex researcher Alfred Kinsey. While there’s not much new data backing up that finding, one 2014 study from Weill Cornell Medical College found the force with which a man ejaculates corresponds directly with how satisfied he feels about his orgasm.
