Listen, the less people have to rely on mods the better.
Piercings, Tatoos, or muscle tones for ALL races, and you basically have 75% covered. That goess beyond only private areas, which will not happen because you cannot strip beyond smallclothes by default. This also means less syncing.

And let's not forget that pierced Fantasy characters is nothing new. TOTK Ganondorf, Any and all orcs, at least 1 sidecharacter or thug anywhere.
Some people use face paint as stand-in for facial tatoos, and some gear literally adds tatoos.

I'd personally add scars.
