Are bisexuals men more manly than heterosexual men?

There is no definitive measure of "manliness," as it is subjective and varies across cultures and individuals. Bisexual men and heterosexual men can express masculinity in diverse ways, influenced by personal experiences, societal expectations, and individual identity. It's important to avoid generalizations, as both groups encompass a wide range of masculine expressions and traits. Ultimately, manliness is not inherently linked to sexual orientation.
