Lol, I had this thought that if every image with a nipple is rated m for mature then how about cows?
We are free to draw their nipples/ teats all day and nobody ever complains about that xD
Simply said, I think the rating on nipples is pretty stupid, unless you live in a box and had yours sanded off as a child I'm pretty sure you know that everyone has them.
Its different if you wanna draw them like, over exaggerated and super erect imo. But dude a nipple, if you are 13 and have never seen a nipple, I dont know what to say, lmfao!
I think of nipples like butts, everyone has a butt. Drawing a butt is not rated M unless you make it all sexual looking.
On that note, does this journal needed to be rated M for mature as well? I wrote nipple, more then once, and btw I come by this question honestly.
Ps: a store near me once got complaints about nipples on mannequins, so they took them down and replaced them with ones that had larger nipples in protest saying, there is a difference! Everyone has them and everyone can see them through you shirt! ( unless you have a lot of layer or something) so whats the big deal?
Honestly, I think if people weren't made to be ashamed of their body the world would be a better place
