I never understood Celibacy

I have never understood Priestly Celibacy. Every argument for it--as in the one that says that a priest has to devote all his time to his flock, to his parishioners--is not only old-fashioned, it's also ridiculous. Such arguments lack compassion--compassion for the priest, for his life and feelings. He does have feelings and he is a real person, a real man, collar or no collar.
