Toilets flat-chested women should not be considered NSFW

EDIT: TYPO IN THE TITLE THAT I DIDN'T CATCH UNTIL I TAPPED 'POST' Why are boobs considered NSFW? ​or at very least, its not NSFW until you can see the nipples, but men have those too. Anyway, if its the boob thats the problem, them flat chested women should be exempt from NSFW rules. If its the nipple, then male nipples should be subjected to the same guidelines.
