Exactly how steamy is this poem?

PG-13

How steamy you think this poem is depends on how much imagination you use in reading it. Here, the question basically boils down to how we're supposed to imagine the scene of the speaker lying with his head on his girlfriend's breast for all eternity. Keats doesn't elaborate much on what's happening here, so we'll leave it up to your imagination.
