Song for a Dark Girl Steaminess Rating

Exactly how steamy is this poem?

PG 13

While we don't actually see any love-making, we get some disturbing emotional content. This poem is about two young lovers. One is physically stripped, beaten, and lynched. The other, the girl who sings this poem, is emotionally stripped and bruised. If not for sex and nudity, this poem needs a higher rating for its disturbing subject.
