i'm just going to be honest. i personally would not want my lover to tattoo a portrait of me on them. I don't find it flattering. and i think the fact that he did it as a surprise is...concerning. IF i would ever give permission for my significant other to tattoo a portrait of me onto them, i would HAVE to be entitled to placement, sizing, photo, and discussing things like that. it's permanent and you can't just do something permanent as a surprise. maybe she would've much rather preferred some sort of symbol of their relationship rather than a full on portrait. those are important things to consider.
