I will not be ashamed,
for snatching this chance  [color=#0000ff]<<I think it is "ashamed of"
not, bound by convention, <<why a comma after not?
or someone else’s
convoluted notion  <<not sure you need convoluted
of morality
I offer no apology, or remorse
for, far more than I fear any
retribution of man or deity
I fear, a lifelong loneliness
a lack of passion,
so extreme
as to be sentenced to endless
monotony  <<I dunno, this seems a bit wordy
I am guilty of nothing, except
coming upon a well spring
of desire, unbidden
and unexpected, having
endured, a near death sleep
waking, to a wanting,
a thirst and hunger,
so deep, and so powerful
I could not ignore it <<maybe full stop and new  verse.
near drowned, I emerged   
lungs burning with the need
for needing air, and I sucked at it,  <<perhaps instead of "and sucked at it"  say  "and drew great lusty gulps"
great lusty gulps, as if reborn,
long caged, the catch failed,
the door fell open,
and I felt the breeze
restore the wings of freedom
I had almost forgotten
I will not settle for the punishment
of a foolish penitent
...this is no confession
