Goblin Market Steaminess Rating

Exactly how steamy is this poem?

PG-13

Most of the sexy stuff in "Goblin Market" is implied, rather than explicitly described. There are some lines that are almost ludicrously erotic – they're so over-the-top that it's hard not to laugh as you read them. Yet Christina Rossetti insisted her whole life that it was a children's poem. So we're going to compromise, and give the poem a PG-13 rating.
