[Sexuality. Cultural, social and clinical aspects]

The deep changes in values, beliefs and behaviour, both individual and group, have been examined, referred to the sexuality, by various methods and prospects. Sexual differentiation, typical of the plast, has been rediscussed and modified. As a result of these changes we can talk about old myths, concerning the conception of sexuality in the past, and new myths that concern the present. In this work we have reviewed the different aspects of male and female roles: masturbation, the obsession abort performance, the orgasm and, not last, the sexuality in old age condition.
