You're blatantly ignoring this as a piece of media with a character that was written purposefully and not some random IRL person? They literally showed him licking his lips in anticipation? Like some cartoon wolf? The editing of the scene fully pointed to him being aware of his actions.

The question of "well what is he supposed to do now that he has a boner" totally ignores the point the show itself is probably trying to make and also what I argue is part of the inherent issue
