I think I’ve become sexist without even knowing and it’s confusing

In real life I’m not. I have no problem with women or their positions, but when it comes to entertainment I feel any interest immediately slip away if the MC is a women. Games, moives, TV shows. It’s actually really frustrating because there have been things I actually have interest in but just don’t care cuase a women is the MC. It’s not like I despise them or anything, I just could not care, in fact it makes me irritated.
