I was in the most conservative Catholic seminary in the country from 1969-1976, and celibacy was never mentioned. Anywhere. Any time.
*shakes head* What a FAILURE of spiritual direction. My b-i-l said that among his classmates, there hasn't been much of a problem with the guys; only a couple left the seminary, but are either deacons, or are still very faithful Catholics. NONE of them have been involved in any abuse of kids or teens.
I suspect a lot of the men who couldn't handle the celibacy part just were not given any spiritual formation in that most important subject.
