Your article has me remembering the history of my catholic upbringing and that lust is one of the seven deadly sins. My Catholic background taught me sex was Kosher, since sexual desire supposedly comes from an evil impulse, mainly female, and only permissible in marriage.
Further, masturbation is forbidden for sperm must not be spilt in waste. The rules handed down from the 13th century governing male and female relationships were despotic. Sexual activities cannot take place on Sundays. Sexual activities cannot take place when a woman is 'unclean' (during menstruation or pregnancy). No sex can take place for 40 days after childbirth, and more.
Shame on the traditional Catholic school system.
