Can she tell me this?

Hi, everyone. Me and my GF were talking about tattoos (I have a half-sleeve) and she asked me if I was going to have anymore done. I told her that maybe turn my half-sleeve into a sleeve and get another sleeve. She basically told me that she doesn't like people "heavily" tattooed and that I should not get anymore done. I told her I was gonna do it probably, and that it's my body (I told her nicely). Than she got upset. And started making weird comparatives, like she tattooing Brand Boyd form Incubus. I think she can't tell what to do with my body. What do you guys think?
