I normally sleep on the left side of my head, so I could get one in my right ear without worrying about that. I think my wife would kill me if I got another piercing, though, especially cartilage, considering what she's going through with her helix. She failed to listen to me or the piercer when we told her how to take care of it and just basically did nothing to clean it, so now she has some pretty gnarly hypertrophic scarring on her ear. I actually joked about it and told her I would get some type of cartilage piercing and not take care of it to make her feel better.
