Excellent points all. But are we on the same page regarding the meaning of the word "sublimation?"
You're right!
I don't know what word I was thinking of, but, yes, I was mistaking sublimate for "secret." It really is more a matter of transform. Though it's so often used regarding sexual feelings that someone can't or doesn't want to act on that it often feels like someone is hiding or running from those (taking up exercise as a way of getting rid of inappropriate sexual energy that you'd otherwise act on, for example).
But that doesn't mean that they're doing the sex and hiding it, or that they're not admitting to those feelings. You are quite right that sublmate means you recognize the feelings, but do something else with them. So, not apt for a priest who acts on sexual feelings rather than one who "transforms" them into prayer instead.
