I do not like the tats or the piercings. I will typically shy away from the girls that have either.
I can overlook the belly piercing, which is so common place now, you'd think girls are now born with them. I can also overlook one, or very few tats, as long as they are fairly small, and somehwhat inconspicous.
My prev fave had NO tatoos and and the only piercings were the single hole in each each and a belly piercing. I really liked that about her. To me, I sort of equate the amount tats and piercings to the level of sleaze. Maybe that's a bit unfair, but usually it seems right on.
My current fave just has the ear and belly piercings, plus a tatoo that is probably about 3" wide that surrounds her belly button. Although bigger than I'd like to see, I can live with it.
