Yeah, my first thought was, "Why kind of girls have you dated before?!"
I have a tattoo. I love tattoos. But, I don't even think I would get my husband's name put on my body anywhere (If I had a husband). Even when I was considering a tattoo dedicated to my mom, it was all symbolic, and not her name.
My thoughts are that either he was thinking you were *way* more into this relationship that you probably were, or he's been bitten before.
