Generally, the more frequently a man an ejaculation, the less force that ejaculation will have. This results in a shorter shooting distance. Most of the differences however appear to be both genetic and age related. Some men are able to shoot longer distances than other men, and younger men tend to have greater force of ejaculation than older men.
The researches indicates that after prolonged abstinence of more than three days a man may be able to shoot three feet or more, but the average is seven to ten inches with more frequent ejaculation. When a person ejaculates two or three hours after his previous ejaculation the semen just dribbles out. The ability to shoot long distance not only declines generally with age, but probably varies somewhat according to the hardness of the erection too.
