Honestly, just do what you like. Even if it means others dislike it. It is not really worth to stray away from your own vision just to please people who basically just use emotional blackmail. "If you do that, I will not play this game anymore" is a shitty attitude and if it results in the creator of the game not being able to create the game in the way they themselves want it, it is really bad.
So go for all the nipple piercings you want, in the end, 90% of people who say they wont play the game anymore will still be playing it, just in secret, lol.
(Personally, I think for a certain someone who has high feministic views it would be even funnier when she gets even more body modification. Imagine turning the feminist into some form of Bimbo or hyper-feminine person with Piercings, Implants, bleached hair, etc... I know this is not the route you want to go, so I dont expect it or would even demand it, but I personally would like the idea of her turning like that...)
