When discussing sex-based social crimes, the fundamental question is raised, that is, why this natural activity, gratifying sexual needs tends to go with so many crimes. Because of this, sex used to be considered a sinful activity in the history of mankind, unless it served the purpose of procreation. In the strict Jewish-Christian interpretation, sexuality can only serve the purpose of childbirth, the pleasure factor being completely excluded from the sexual act. Among ultra-Orthodox Jews, in practice, couples were even separated with a clean white sheet to avoid touching and seeing each other during the sexual intercourse and only a hole was cut into the sheet to include only the primary genitals to take part in the sexual act, because the sight of the female body was considered the source of sin itself, though many consider it a legend. The feminine body was associated with evil, the appearance of the devil, in an attempt to get the pious on the wrong path, so it is no wonder that wherever possible it was hidden, covered and in the extreme example mentioned above, even spouses were restricted from sight.
