Nope, looking at porn is a strict no-no. Jerking to porn, as an elder commented, is the same as adultery. You looked at the naked person with enough lust to get aroused and then climaxed. Time for the back-room inquisition. Of course when his own kid got caught sleeping with a "worldly" school friend it was no big deal because he "didn't climax. So it is only loose conduct, not fornication!".
Can't make that s--t up!
