If you are putting a hole in your face, I suggest you put it where you want instead of where you think a guy might want it. Think only about your preferences, not a theoretical guy's.
As with all decisions in life, do what is best for you. If you want to get a piercing, think about where it would bother you the least and look the best. Do you want to deal with that lip ring making it awkward to eat for the next two weeks? Or would you rather deal with getting your eyebrow stuck in your tshirts for the next two weeks? If neither would be a problem, then just pick what you think would make you feel the sexiest.
Weigh the consequences, both in terms of convenience and fashion, and then go to the piercing parlor. Leave guys out of it.
