Answer:
The best thing to do would be to steal the diary of a 14 yr old girl - it should be full of sticky-sweet love poems. If your school has a literary magazine that would be a good place to check. Also, the internet is full of poems by teenagers who think they can write. Just type "poetry" in Google and follow the first link.
I could be misunderstanding your question though. If you really meant "How can one hear teenage poems and survive the experience?", the best solution is to cover your ears. If you were asking where to find good poems by teenagers, then you're out of luck - poetry as an art is dead.
