I don't know, there are times where I myself get shocked. I use Crammyboy's realistic mod for guys, and last night one of the professors jumped in the love tub naked. I hadn't set his options, so he was a dark-skinned elder male with a pale white thingy. He even stood up and greeted his date like that! That was their first date, BTW. She wasn't shocked, but I had to gasp and blink a couple of time. Then I set his options and made him look better. LOL But it was hillarious.
LOL ^^
If any of my simmies ever get naked like that, no matter how outgoing they are, they never just walk around that way. After a few seconds they always change back into what they were wearing.
