If the tattoo is fairly small and delicate, and located somewhat discreetly like on the ankle or shoulder blade, I can live with that. Tramp stamps, not so much. "Sleeves" are out of the question.
Piercings are kind of the same to me. I can live with a small nose stud. A stud on the lip, perhaps. Rings and things decreases the chances. And tongue piercings? Well, they say they are good for one thing...
I can understand how a woman wants to be an individual, but it's another thing to stand out too much. As long as everything is tasteful, I guess that's what I'm trying to say. And she knows how to properly use the tongue stud.
