The poet's major stylistic change in his shift towards free verse roughly within a decade that included much of the 1960s, combined with the other changes in his life — his move from England to America, from academic Cambridge to bohemian San Francisco, his becoming openly gay, his drug-taking, his writing about the "urban underbelly" — caused many to conjecture how his lifestyle was affecting his work. "British reviewers who opposed Gunn's technical shifts blamed California, just as American critics would, later on, connect his adventurous lifestyle with his more 'relaxed' versification," according to Orr, who added that even as of 2009, critics were contrasting "Gunn's libido with his tight metrics — as if no one had ever written quatrains about having sex before".
