An unprecedented source of information about sex and sexuality at the start of the 21st century, these volumes include research, current events and new developments in subjects ranging from hypersexuality, sex for the aged and sex therapy, to orgasmic disorders, sexual fetishism and sadism. Controversial subjects such as pornography, nude dancing and prostitution are explored, as are dysfunctions, from lack of sexual desire to gender identity disorder. Paedophilia and other crimes are also addressed. The team of authors includes psychologists, sociologists, psychiatrists, medical doctors and public health officials. New views are offered spotlighting sex today, sexual development in childhood, midlife and senior years, and influences of media and family in the social construction of sex and sexuality. The books also offer insights into the effect of medication and drugs on sexual function, into the psychology of sexual arousal, and into such little-known studies as those of sex and race, and sex and religion.
