Considering the fact that you used the wrong tense instead of write, I'd say an accurate one.
What kind of poem should I wrote to get a girlfriend?
The soppiest, most romantic, most embarrassing love poem you can muster :-)
Firstly, learn how to write. This isn't a life long process like many will tell you. Read the gods and the geniuses. Don't worry about the rest, the boring, the rabble, although, they can help too. Think about the French poet Arthur Rimbaud changing the course of poetry by the age of twenty.
Think of how you've always got a chance in any situation, and even if you haven't, that doesn't matter, as long as you place every gram of your being into your heart, and learn what your strengths are.
In time, if you do this, whether poetry or not, you will be able to explain your passions, desires, observations, and insights, in an organic, personal, and simple way.
This is how all of the best love poems work. Although ironically, you may find that you forget about 'getting a girlfriend' in this process, if you study the greats, and find that things fall into place regardless. And also, good luck bud.
