This man asked "Who would believe me, if I swear / That I have had the plague a year" in one poem and noted that he was a "little world made cunningly of elements" in another. Aside from writing "The Broken Heart," this poet noted that the title figure "suck'd me first, and now sucks thee" in a poem that uses being bitten by an insect as a euphemism for sex.
