I've sat in on a tattoo with a lady that has had this done. She was very open and happy to talk through not only her operation but give us a good look at her scarring and the nipple darkening work and also had her phone out showing us pics.
A very brave and lovely woman and if this sort of work gives them a bit of their confidence back and helps draw attention from their scarring then its all good as far as I'm concerned.
The tattoo we did was on her ribs and nothing to do with this procedure I must add. We just noticed her scarring and got talking about it. I certainly wouldn't class it as female body enhancement.
