This also comes from the fuzziness of the boundaries. Many men who are attracted to other men will not admit they are bisexual or homosexual. This is why the term "MSM" aka men who have sex with men is sometimes used. It is easy to find conflicting stats because sometimes the definition used is self-identifying homosexuals, people asked if they are MSM, or physical arousal tests. The self-identified definitions are all part-right, since self-identification is disincentivized, but for the sake of science the clearest definition, and one of the smallest estimations, is probably the one we'll see used.
