I recently wrote my girlfriend a poem, it didn't take me long. I am not the most gifted person when it comes to poetry, but it came from the heart and she appreciated the time I spent writing it. So instead of asking someone else to write you something to woe your woman with, just stop, think and spend some time thinking about her and you. It may not be shakespeare but believe me, she'll appreciate the effort and the personal touch. Stop being lazy/apathetic/uninspired and think what it is that makes you love this girl, and then put it in words.
