You missed the context, Sam. My point about the pinky was in response to flatbusher’s dismissive comment about “something lascivious about a male looking at the picture of a woman”. Yes, we are worried about the possibility of something lascivious about a male looking at the picture of a woman just as the Gemorah and the Mechaber are worried about the possibility of something lascivious about a male looking at the pinky of a woman.
And, frankly, I think there is a lot lot more to be worried about men getting lascivious about a picture of a woman than of a pinky of a woman. The picture they can stare at longer and take with them in privacy.
And Charlie is dismissive of kol kvudah bas melech pnima by brushing it off as merely “referring to a non-Jewish woman”. So I pointed out that the Mechaber was not referring to a non-Jewish woman when he cited kol kvudah bas melech pnima in the S”A as halacha.
