I think they can be beautiful, on either gender. I think they can look like total CRAP on either gender. If it's terrible work, it is just marring up the body to say "duh look I got a tattoo--real cheap!" Yeah, no kidding.
I also would say that looking at the type of tattoos someone has can tell you some things about their personality, likes, dislikes, etc. Some people go for total shock value and have a lot of vulgarity, hey, we are all different, some are actually quite disgusting--to non-like-minded individuals.
Someone said the other day how their parents are totally against it because it's destroying the temple(body) I prefer to look at it as decorating my temple. I wear all black, so to avoid the pasty white girl look, I have color.... lots of beautiful, vibrant color. Makes me feel good about myself. I'm a professional musician, and people take pictures of me all the time, so instead of them getting pictures of short sleeves with my huge beefy arms, they see my colorful, beautiful tattoos. My boyfriend loves them!
