What? Roughly 7% of men in Western culture are not heterosexual. Across the rest of the world, 3-20% of men (depending on region) have had sex with men.

Recent figures for young adults (i.e., 18-29) identifying as trans / non-binary in the US are in the ~5% area, which suggests that figures historically would have been higher had there been more cultural awareness and acceptance.

“Surveys in Western cultures find, on average, that about 93% of men and 87% of women identify as completely heterosexual, 4% of men and 10% of women as mostly heterosexual, 0.5% of men and 1% of women as evenly bisexual, 0.5% of men and 0.5% of women as mostly homosexual, and 2% of men and 0.5% of women as completely homosexual.[1] An analysis of 67 studies found that the lifetime prevalence of sex between men (regardless of orientation) was 3–5% for East Asia, 6–12% for South and South East Asia, 6–15% for Eastern Europe, and 6–20% for Latin America.[4] The International HIV/AIDS Alliance estimates a worldwide prevalence of men who have sex with men between 3 and 16 percent.[5]”
