It is blind obedience [and stupidity] not to challenge both the theological rationale in both the Catechism and Canon Law.

I teach church history---the concept of celibacy was first brought up by Spanish synods in the 4th Century.  But this concept was not widely enforced.  Pope Siracus believed that engaging in sexual contact [and remember that priests, bishops and popes were married], caused a minister of the altar to be 'impure' in celebrating the Liturgy.  He insisted that in Rome all priests be celibate.  Eventually, by the year 1000 AD this became the practice and DISCIPLINE in the Church.  In the Apostolic times---and the Apostles themselves, were married.

Married love and sexuality is not dirty, impure, demeaning or any other degrading term.  In our time, any concepts such as this should be condemned to the hilt.  AND, we have absolutely NO EVIDENCE that Jesus was not married [he could have been a widower].  It was the task of Jewish parents to secure a wife for their sons.
