>So just to clarify once and for all, it's not sacrilege against confession if I don't tell him what exactly I lusted for
The general consensus from googling a bit seems to be that you only need to communicate the number, kind, and gravity of the sins. "Gravity" doesn't seem to mean how bad as in how disgusting, repulsive, degenerate, etc., but rather how serious a hold it has over you.
