A Brigitte Bardot will look at sex in her own way, and so will the courtesan. The average citizen may not identify himself or herself with any of these interpretations but will have his or her own concepts and ideas as to what sex means or should mean. The biologist, the medical man and clinician, the psychologist, the jurist, the sociologist, and finally the priest and theologian are all apt to view and study sex from different angles and in different lights. The object and purpose of sexual relations varies with various persons and under various circumstances. In the animal world, the sex urge is the instrument for procreation.
Animals fornicate instinctively for that purpose only.
Humans do not do so as a rule. But most individuals seek pleasure in sex or at least seek relief from unpleasant tensions. More and more persons realize that sex serves recreation as well as procreation. But such is rarely admitted and rarely taught in any schools, including medical schools. Sexology as a branch of medicine is still rather widely ignored in formal medical education, to the great disadvantage of the young doctor and his future patients.
