Filthy Poets

The 2nd Earl of Rochester, John Wilmot, wrote filthy poems. That is all I've learned today:

Have you not in a chimney seen
A sullen faggot wet and green,
How coyly it receives the heat,
And at both ends does fume and sweat?

So fares it with the harmless maid
When first upon her back she’s laid;
But the well-experienced dame,
Cracks and rejoices in the flame.
