Although he may not know it, a man doesnt have to have an ejaculation to have an orgasm. This phenomenon was first noted in 1950 by the famous sex researcher, Robert Kinsey. Since then, modern sex researchers have learned that some men do not have an ejaculation until several moments after they climax, while other men during a protracted lovemaking session will have an ejaculation and an orgasm, and then go on to have, within that same lovemaking session, more orgasms, but minus any further ejaculations.
Men who do not have ejaculations report they have other physiological experiences that can still be called orgasmic. They describe sensations of intense pleasure building up within the scrotum and genitals, and then a sense of release. Others will feel a pulsing throughout their entire bodies.
How much of these sensations are physical and how much psychological is hard to say. Either way, men who do not ejaculate still report at the time of their climax less voluntary pelvic thrusting and a contraction of the muscles of the penis. They also experience elevated heart rate, blood pressure and respiration. Because a man doesnt have an ejaculation, it doesnt mean hes not experiencing orgasmic pleasure.
