I don't think he does, but then again, I've only seen him with his shirt/pants on.
If he did though, and I saw it/them, it totally wouldn't bother me. I HATE that *I'm* constantly being judged because of how I look on the outside. I want, just for once, to be seen on the inside, and for the outside to not matter (I mean IRL...I'm good to go in therapy). I have a tendency to look beyond outward appearances with people, and immediately look at their character (because that's how I want to be seen), so no, a tat would not bother me.
