""Walter" was not Henry Spencer Ashbee. Only Ian Gibson thought they were the same, which only shows that he has no notion of chronology,and a cloth ear for writers' styles.
Walter has been convincingly identified as a military officer, of no distinction except for having written his memoirs.
Ashbee was a bibliophile, and a much better writer than "Walter" (and utterly different in style), but he had no sexual experience.
Ashbee quite possibly died a virgin, while "Walter" quite clearly was not writing porno fantasy, but real - and often unflattering - experience, a sort of sexual Henry Mayhew."
