This is totally different from emo.

Them selves.

Um....maybe someone who's being themself instead of trying to fit their particular desires. Why do you want a "punk" so bad, anyway? Are you generally a good girl who just wants to shake things up a little by getting herself a "bad boy"? Perhaps you should just try to find someone who appeals to you, rather then try to appeal to someone else.

I guess It really depends on the particular guy. Come "punk" or "rock" guys are looking for a wild child. It really depends on nature and nuturuing. Nature meaning we are all born with certain things me prefer and nurturing meaning as we grow up our taste changes because of the things we experience. For exmaple: If the guy you are going for has a bad relationship with his mother he might look for those characterists, she lacks, in you. A guy that acts like he has it all together might go for a wild child to spice it up but he may have internal chaos and look for someone who is realiable and caring.

Same things normal guys like, just with more accessories

in my personal opinion ,they like sweet girls because they need love .they always (not always),sometimes look for someone to love them the way they are.
