I really want to do just what my body wants to do.

Just repeat until the part where he sings "I need to do" over and over.
The chord for the "I need to do" part is just G. 

Basically the chords just repeat until the end:

F G C G 

Play along to the song and you'll get it. It's pretty easy but sounds great when you sing along!
I hope its not too confusing
