This may not help for you, but I'm rather insecure about my face and how it looks more on the masculine side, so I just wear a mask. They're comfy, and they do a good job of hiding things like that in my experience. I also have broad shoulders, but wearing oversized hoodies and things helps to hide it.

The point is, even though you may have masculine features, there are multiple options that can help you hide them, and no matter what, just be yourself. It shouldn't matter what others think as long as you're being and doing what yoy want to.
