I think a tattoo can be a definite turn on; they can add the whole 'rugged' look to a guy - which to me is a total turn on. However - they can go too far.
Something small and simple is good. Maybe with some kind of meaning behind it, maybe not. And something discrete - we don't want a walking, talking canvas' arm to hang off.
Of course, as most things to do with appearance it is subject to opinion, and for some girls a tattoo won't do it for them at all - but if you are comfortable in your skin - and whatever happens to be on it - your confidence will show.
i like tattoos on a guy anywhere on the body (maybe except the dick, thank you) as long as it's artistically thought through and done.i don't like something that hasn't been thought through (like a barb wire or whatever as cheesy as that). I was from a design school, so tattoos to me are like a piece of art, so the more artistic it is on a guy's body, the hotter it is. the standard of the ink work also plays a part. it's especially hotter if a guy designed his own tattoo himself (like my boyfriend did) :D
Some girls do and some girls don't. I do and I think they're nice everywhere except above the shoulders. I think it looks trashy on the neck, face, or head. I think it looks cool if it's on a guy in a band that I like, but not on someone I would consider dating. Sounds shallow but it's just a preference.
I've never liked them. When I first started dating I associated them with drugged out bikers and now I associate them with the worst stereotype of a frat boy on spring break. I think I missed a time in between when cool people probably had them, but whatever, that time is clearly gone.
I personally find it very attractive, I think they're hot. Especially full sleeves, but I kinda like it when a guy has a tattoo in his neck too, heh. Though they have to be designed good, the more unique they're the better.
i usually think tattoos are ugly and trashy, although I LOVE ryan sheckler's tattoo that is on his back. other than that, if its a small tattoo it can sometimes be okay, as long as it is something meaningful, not just of something ugly and pointless.
