I happen to like tats...
I don't have any, but I think the right one can look very sexy.
But hey, that's just my opinion ;)
Of course, the desirability of the tattoo is inextricably linked to the suitability of the canvas...A bad tattoo can make a normal person look like a crack-head.
I've always loved pure skin. Sometimes G-d decides to add and I don't complain about what He does, but I've never understood why anyone would think they could improve on skin.
Shalom.
