Im confused.

I think that this r doesnt get much questions, but i have a few questions about the genre itself. So ive been loving bara since 2020 i was fascinated by the art and culture, it really made me appreciate being gay and still does but i have a few questions about it.

The meaning i understood from multiple hours of research and looking at art is that its gay muscular guys, and that's it. But yet some people draw straight couples and call it bara. ???… Im confused. Im not saying women shouldnt enjoy bara, but yaoi with a woman doesnt exist so how does bara with a woman exist exactly? Is the meaning of bara flexible? Let me know, im curious.
