The reverse has been true and openly discussed for ages, there’s a reason the “sassy gay best friend” is such a trope in shows and movies made for female viewers. A decent percentage of our conversations with friends has to do with our attraction to or problems with our desired gender, so being able to commiserate with someone that has the same preferences also encourages these friendships. There’s just an extra layer of relatability that hetero mixed gender friendships don’t. It would be odd to point at a stranger while out with a heterosexual female friend and say “look at that chick, isn’t she hot?” Your friend could potentially think you’re trying to say that if she were more like that chick then maybe you’d want to date her. Even saying something like “women are crazy” has a very different tone when said by a man to a straight woman.

I got Portland too!! I’m bi but I mostly listen to Spotify at work where almost everyone else is gay haha
