If a priest or nun should choose to have relations with a consenting adult, that is their own business.They made a vow and if they break it they have to live with it.
The problem comes from priests who prey on boys! They should be treated like pedophiles because they prefer children over adults.
The priest in MA is a perfect example. If he was a librarian or a teacher he would still prefer young boys.
Don't change religious traditions because of a perverted sickness. Get rid of the problem quickly and permanently.
If this priest in MA is not put away till hell freezes over, he will do it again and again.
