I have four, and wish I had a lot more. I'm also more attracted to girls with tattoos.
I prefer uniqueness, and tattoos are a good way of distinguishing someone from everyone else.
Granted, the tattoos themselves have to be original. I'll admit I have a band logo on my leg, but otherwise my tattoos are designed by my artist so that they wouldn't be seen anywhere else but on my skin.
I don't kill... but I don't lose either.
