Is it ok to actually be like a child?

I'm a boy. I could be serious if needed, I think I truly am like a little boy at the core. But is it unhealthy or unsustainable? By it I mean that I would love to constantly be in a dynamic where she's the mom and I'm her boy. My mannerisms are childish, I would be clingy, I'd ask for her permission for everything, I'd give all power to her. Like a human puppy. But is that just a fantasy that can only be true for a short moment every week, or could it be a constant. Because I just am like that as my true self and I hate acting like an adult. I'm autistic and mask at work. I would do my best to be in a position where I could come home from work and immediately be myself with her. I forget that I even was at work and now the only thing I know is that I'm her boy. Is it just a hopeless dream?
