I had a tattoo back when i was in the army. I don't regret it and i still like it. The reason? i chose something from a subject that I liked since i was a kid, it was my own design, and, even though it's not small, it's on my shoulder-blade so it's not something that i cannot hide. But I am a dude.
As for women, i do see the art in it, and there were a lot of occasions when i was amazed by the beauty of some tattoos on women, but, having a tattoo that would fit on a 5' by 3' canvas on a woman's back is not something i consider neither sexy nor appealing.
