I assume you are talking about the rant in The Road to Wigan Pier. Orwell was certainly culturally conservative and by "sex maniacs" he did mean gay people but also heterosexual free-love enthusiasts. Orwell's ideal of a socialist (which he describes in the book) is a man who works in a factory who has a stay-at-home wife who takes care of his children and who likes solidly "English" things like eating beef and drinking beer. He didn't like the counterculture at all.
