“It’s pretty rare—but it does happen,” says Dr. Barry Komisaruk of Rutgers University, who published a landmark study in the Journal of Sex Education and Therapy in 1998 describing a man who experienced six full “ejaculatory orgasms” in 30 minutes without going soft.

He conducted the research with Dr. Beverly Whipple, the scientist famed for proving the existence of the G Spot, and freelance writer Brent Myers, who introduced Komisaruk and Whipple to the exceptional man in question.

He was the first ever described in a scientific paper who could climax, ejaculate, remain hard—and keep going. Prior to this, all scientific studies—including those released by famed sex researchers Masters & Johnson—claimed that repeated ejaculatory orgasms without a “refractory period” (read: a limp period for recharging) were next to impossible.
