Pay up. The reason had nothing to do with "touching Christ" as you contended. Like all celebrants he couldn't eat or drink the night before either. It was about sacrifice. By the way it wasn't until 325 (Council of Nicea) that ordained priests could not marry.
So sex made them too dirty to do WHAT SACRIFICE ? duh... the bread
385-Pope Siricius left his wife in order to become pope. Decreed that priests may no longer sleep with their wives.
567-2nd Council of Tours: any cleric found in bed with his wife would be excommunicated for a year and reduced to the lay state.
590-604-Pope Gregory “the Great” said that all sexual desire is sinful in itself
Slight correction. Priests were still permitted to be married long after 325. If married before being ordained (they could not marry after ordination), they were expected to be continent/abstinent in both East and West until the East changed in 695. The West forbad ordination for already married men only later (because married priests were not obeying their continence pledge) and only really enforced the prohibition of being marred (celibacy) in the 1000s.
