It's one thing to be a fan / geek / whatever, but this is on a whole new level mate. In my opinion, I see this as heavily detrimental to a normal life. I worry why a man of 32 feels the need to immerse himself so completely, and to physically mark themselves in such a way with stuff from a fantasy comic.
If you haven't to spoken to someone already about why you feel the need to escape so completely from your real life and transport yourself to a fantasy land, I would suggest you do so.
I'm not having a go whatsoever, just genuinely concerned as your behaviour is not usual. It would be interesting to find out quite why you have latched onto a fictional, american cultural icon. I do strongly suspect it has something to do with your childhood, but only you know quite what.
