Is he really an ally or…?

My (24F) boyfriend (24M) knows I’m bisexual. He claims to be an ally and claims to be supportive but I honestly think in his head he fetishizes it. He subtly jokes about a threesome or girls we should “bond over being hot”. Never blunt, never asks for one, just jokes about it being any dude’s dream. Well, I fully expected him to say happy pride to me or something and he simply didn’t. Instead he posted on his Instagram about Men’s Mental Health Awareness Month and had no mention of Pride even though he knows it’s a big deal to me. Is he really an ally? What do I do?
