I'm afraid that it's pretty much too late, and the damage is done. I can't see any parent of a Catholic teenage boy EVER looking at any priest with the trust that was given in the past.
I am one father of teenage boys who cannot. I will never allow my teenage sons to be alone with a priest, EVER. I have had to explain to them, reluctantly, that a good portion of the priests in the Church are homosexual, a good many are active homosexuals, and a not insubstantial number are homosexual teenage boy molesters. I abhor the fact that my sons have been forced to contemplate this (before they have even developed a good perspective on normal sexuality). Further, I have NO FAITH in priests teaching my sons about authentic Catholic sexual morality. The Church is entirely responsible for grossly devaluing the esteem with which people hold priests.
