Orgasm refers to a reaction stage of sexual behavior, in which the body will involuntarily have a series of physiological sexual reactions. Among them, the breathing, heartbeat and blood pressure of men and women increase sharply, the muscles of the whole body contract, and the muscles of the sexual organs contract rhythmically. Men will ejaculate, and a small number of women will also ejaculate some secretions from the urethra. Orgasm is a physiological reaction and will also bring great pleasure. As for whether it is the "highest pleasure", it depends on personal opinion. After all, sex must take into account the needs of love, care, and emotions. Pure physical satisfaction is not everything.
