In Vatican II days, seminaries were overly alert to homosexual acts, which brought immediate explusion. But we never named anything as sexual. There were in most seminaries a divide between straights and gays, but neexpulsionver acknowledged as having anything to do with sex. We were very, very naive, and nobody had to identify their orientation. Yet, the statistics show that the great majority of  ordained priests from both orientations have been equally faithful to their vows (many of the straights left long ago!) and served their people empathically. If these "exclusions" were ever to be actually enforced, they would effectively exclude about half of the priests.
