Before I go to pee or poop I always check behind the shower curtain to see if there is anyone behind it. I CAN'T HELP IT. I HAVE to do it! No matter how urgent it is, I ALWAYS check! Even if I know nobody is in the house, I still check. Also, if the shower curtain is open I always close it before I go. It just feels like someone can see me through the wall with the shower curtain open. Is it normal to be this paranoid???
