while we're here let's clarify: femboy is a term that only applies to a cis straight male who wears clothes women typically do. its just the guy version of tomboy. And tomboy specifically exists because people needed a way to say "yes, despite the not-very-girly dressing habits I am indeed a cis straight girl" but we used less technical terms in the past. "Femboy" has absolutely nothing to do with LGBTQ whatsoever

Every webpage says the same, originally it was an aesthetic/gender expression for more feminine guys, later it was inherited into the LGBT+ community, as most of them are homosexual, but not all.
