Well, this is useful; we’re clearing up some misunderstandings about this thread. I hope you’re finding it helpful, too.
Let’s take two possible scenarios:
(A) Fr. Bob hears confessions on Saturday. During one of the sessions, a penitent confesses that he has lustful thoughts when he watches women’s beach volleyball. Fr. Bob thinks to himself that, with the Olympics on, this might be a common problem, so he decides to address it. As luck would have it, the Scripture reading for the next day (Sunday) includes the “If your right hand offends you, cut it off; better to enter the kingdom of God one-handed than with both hands to enter the fires of Gehenna” passage. So, during the homily of the Mass, he preaches about lust. “Some of us can be subject to the occasion of sin from everyday events: a beer commercial, an ad for lingerie, and so on. One man confessed to me recently that he has lustful thoughts watching beach volleyball. This is an occasion of sin, and the way to address it is to avoid the occasion: put down the magazine, turn off the TV, go into the other room, or whatever you have to do.”
(B) Fr. Bob hears confessions on Saturday. During one of the sessions, a penitent confesses that he has lustful thoughts when he watches women’s beach volleyball. Fr.

(I think it’s clear that we’re all on the same page that he could never single anyone out, so I didn’t write a scenario with that happening).
Scenario (A) is problematic, because it’s possible (given a small enough congregation) that someone might figure out whom he means. Scenario (B) is perfectly proper: from his comments no one knows that the beach volleyball thing came from confession.
