It's quite funny when I think about this actually!
My boyfriend doesn't have any tattoos, although before we got together, mine were a good talking point and he expressed his interest in getting some. He seemed to have his heart set on two. Since then, I have gotten a big piece on my thigh, and he doesn't seem as bothered to get any himself. He used to be heavily involved in the local metal scene, and I guess that being around tattooed people may have sparked his interest, but since he has turned his focus to education and work, this interest has dwindled.
I don't mind him without tattoos, and he likes mine (I came with five, so it wasn't like I have radically changed on the ink front since we got together). Seeing as most of mine are hidden by clothing, they aren't in his face all of the time. Most people presume I just have the two wrist ones, and seem surprised when I confess to the hidden four!
