“Since the experience is different for each individual, the tension will reflect that experience. In some persons the whole lower half of the body is relatively immobilized and held in a passive state; in others the muscular tensions are localized in the pelvic floor and around the genital apparatus. If the latter sort of tension is severe, it constitutes a functional castration; for, although the genitals operate normally, they are dissociated in feeling from the rest of the body. Any reduction of sexual feeling amounts to a psychological castration. Generally the person is unaware of these muscular tensions, but putting pressure upon the muscles in the attempt to release the tension is often experienced as very painful and frightening.”
