I'm pretty heavily covered but my boyfriend has one tattoo, that I did for him! He says he wants more though, but honestly at the moment only from me. He doesn't bug me much and I don't push it (be was a bit of a little bitch when I tattooed him!) . He has some good ideas I think other artists could do much better justice to than me (I'm very early career!) I'm avoiding scribbling all over him. Haha. He definitely doesn't share the passion for it that I have.

Had to reply to this as I'm in the same situation. Been with my fella 5 years now, and as I mentioned he only has one tattoo. I did go through a bit of a crisis of confidence when I started tattooing, it was such a sea change for me, I had to consider did I want to be with someone who didn't share this all consuming passion with me? Since then I've realised I don't need him to. I have friends and colleagues for that. What's more important is that he loves me, and that he supports my decision to become more heavily tattooed (and he looks after my useless ass) . He's said he finds my tattoos attractive but what's funny is he doesn't like me dying my hair,(it's not a huge deal) which I find funny because that's not even permanent!
