Yeah it's more of the case that very feminine guys are usually gay rather than gay men are usually very feminine.

Two people I knew in college, 

The first, let’s call him Luke. he was a work friend of mine there on campus and another coworker tells me that Luke is gay, right in front of him, I thought he was joking at first but I saw their faces not even flinch about it and I had a hard time wrapping my head around it, I had known him a few months, He didn’t act gay at all! I had a lot of respect for him for owning it and not feeling pressured to act super feminine. Some traits slip through sometimes but it’s not obvious.

The second, let’s call him Anthony. He acted very feminine, he had a bodybuilder build, and was very well groomed in his eyebrows/facial hair. Everyone in our class would ask each other “do you know if he’s gay?” Nobody knew, as we got to know Anthony, he took plenty of interest in girls and even told us his weekend one night stands with various girls, so we figured, ok he just acts feminine but he’s not gay. A couple years later, he makes an Onlyfans that includes guy on guy action, turned out he was actually bi.
