Kinsey's methods are called into question by some, but the impact of his study is actually listed by a few sources as a groundbreaking change in perception about sexuality, and I seriously considered including it in the article. Hooker's study specifically asked men about their own self-satisfaction and happiness. I get your point - at least I think I do, but Hooker's work is cited regularly as the beginning of a change in ideas about homosexuality. I'm reflecting Hooker's work with due weight since it is mentioned by the sources I read. I'll be happy to take ideas about wording and syntax, though.
