If my T has a tattoo, it isn't where I can see it which is fine for me. I'm not a big fan of tattoos. I really don't understand the appeal, but to each their own I guess. I probably wouldn't have a problem with a small tattoo on a T, but I know I would have issues with excessive or excessively large tattoos. The same with piercings. Just a huge turn-off for me. (And please don't be offended if you have tattoos or piercings. I'm just being honest about my personal preferences.)
