Sexual and gender identity disorder: full range of human sexual thoughts, feelings and actions that are generally regarded as abnormal and dysfunctional. Sexual identity our sense of ourselves as male or female. Sexual orientation our preference for the sex of a partner. Transsexualism people with gender identity disorders are sometimes referred to as this; they feel deep within themselves (usually from early childhood) that they are of the opposite sex. Transvestism cross-dress for sexual pleasure but do not identify themselves as of opposite sex (gidnos) They may want to pass as a member of the opposite sex or even have surgery. Gid is different from gidnos (gender identity disorder not otherwise) since that involves symptoms that meet gid but there are some symptoms that do not. In childhood associated with cross-gender behaviours dressing in opposite-sex clothes, preferring opposite-sex playmates, and engaging in play that would be more typical of the opposite sex.
