how much nipple is too much?

“I use myself as the model in front of a mirror because it saves paying someone else and I paint late at night when I cannot expect another model to pose for me.

…I feel sorry for the artist, sitting with the curators of this gallery, with whom she has an existing long term relationship, and candidly discussing how much nipple is too much…. as some of you know I’ve given long thought to nipples, they are a recurring theme in my works in a “now you see them now you don’t” sort of way and I frequently feel they can make or break a piece.
