Its a little bit like the old Incredible String Band song - see layers of the onion album.

Sexual death in 17th metaphysical poetry, death was another term for orgasm I seem to remember.

Also in the modern William Empson poem:-

Not but they die, the teasers and the dreams

anybody studying poetry anywhere might have written this poem, used this metaphor for death. I dunno, its 40 years since I was a literature student. But thats the first thing that occurrs.

best of luck
