Catholic Priests must be unmarried, male and willing to remain celibate. The origins of the vow of celibacy are unclear. The vow has been mandatory in the church since the 11th century. The first Pope, St. Peter was married and up until the 12th century there was abundance of married priests.

Pope Francis in 2010 commented on the vow stating, that celibacy "is a matter of discipline, not of faith. It can change" but added: "For the moment, I am in favor of maintaining celibacy, with all its pros and cons, because we have ten centuries of good experiences rather than failures.... Tradition has weight and validity."

"The Nordic Model of sex work, decriminalises the sale of sexual services while criminalising their purchase along side practices like pimping and brothel-keeping.

By contrast the 'Legalisation' model adopted in Amsterdam allows for the buying and selling of sex by workers as independent contractors, as long as it is done so in regulated brothels. These sex workers typically earn 40-50% of what they bring in with the remainder going to the brothel and its management."
