Coitus reservatus
Some men claim to experience orgasm without ejaculation while practicing a technique of sexual intercourse known as coitus reservatus or "karezza" (ital. carezza = caress). A man who uses karezza tries not to move his erect penis very much once it has entered the vagina. This procedure aims at a spiritual union of the sexual partners who are said to reach thereby a prolonged state of bliss with repeated orgasms. However, it rather seems that at least the men remain in the plateau phase which gives them adequate satisfaction. Their "orgasms," which they may very well experience as special climaxes of intercourse, are not identical with the physiological process discussed here.
