So that's the first and biggest problem with the celibacy rule. You're going to attract a whole lot of people to the priesthood who are running away from themselves-
People who are confused, immature, cowardly.
And the second problem is that you're attracting them on a false promise. The Church isn't the refuge from the world they think it's going to be. The new priest is the man he always was- with the same old urges- only now he can only satisfy them furtively. Shut the door on sex and it'll walk through walls to find you. So there you are- you and your sexuality- and instead of having the whole wide world to prance about in you're locked up together in a teeny-tiny cell.
