No covering. If it is someone who was supposed to see me naked then I have no need to hide from them. If they weren't, my hands will be fully engaged in retaliation.
Well, the vagina being covered in any case since it is the part that starts at the entrance from the vulva and that ends at the cervix, that part needs not be covered since it cannot be seen.
Thus, the correct answer should be the VULVA and the breasts.
Interesting question. When I see videos or news reels of naked or near naked people being ushered into a paddy wagon following a police raid, most are trying to cover their faces.
