DY: There’s no Kreiva L’Arayos by watching a movie. EThe Az Nidb’ru has several Chiddushim in there, but even if we agree to all of them there’s no Kreivah because the movie makes me no closer to the actress. Other Issurim, sure, but not a Yeihareg V’al Ya’avor of Kreivah L’arayos.
If what you’re saying is true, then that means some Achronim hold that one should commit suicide if he knows an inappropriate thought will pop into his head. Hence, absurd.
