Most Helpful Girl
I'd avoid a poem. Any time you're not covering your whole back people will be asking you about it, what it says, what it is, what it's about, all that sh*t. It's beyond annoying after a few months, or a few weeks depending on your tolerance. It's better to go with pictures so people don't ask you to stand there for what feels like forever while they read the whole thing.
Words and short phrases are okay, but if you're going for something big like that do a picture, something that really means something to you, that people can look at and appreciate not ask you to stop and stand around while they try to decipher what's on your back.
As for sexiest? My boyfriend says:
I'm pretty impartial. Tattoos don't really add sexiness to a person, they're just ink on flesh I can't see how that would make some one more appealing, or be appealing in itself.
