Personally, I'm not to fone of tats on my body. Although, I did give it some thought, but ultimately its not for me because how I imagine when I'm old.
On other man or women, I like the artful and creativeness displayed on the body.
I mean getting a tattoo is not gonna give you an easier time trying to pick up the ladies. If you're appealing to them, then you'll appeal to the ones who like tattoos, I guess.
Also, I'm assuming, that just like men, there are girls who like them and girls who don't.
I don't think it's the tattoos but the way you choose them. Such as, if you have a musical note on your arm, then you look harmless and not so tacky as oppose to someone whom chooses skulls, knives or whatnot.
If you sleeve your arms in tattoos you will definitely attract a certain type of woman. I don't mean that in a moralistic sense. Girls with tattoos tend to like men with tattoos. So if you like women with tattoos, there you go.
