Question for fiction writers

I’m what is called a pantser like Stephen King. I don’t outline the story ahead of time. But I do take time to stop and think or journal on where I’d like my characters to end up. Anyhow, my two characters, a woman and a man, are growing in separate places right now. The guy’s growth is far more interesting than the woman’s. In real life this normal since women mature at a younger age than men, but in writing is this ok? Should I find more balance? Should I be more deliberate about her growth? My only concern is that she will be unrealistic if I am too deliberate. Or am I over thinking and this is how characters grow in fiction.

Fiction writers, do you find this or do this intentionally. Like, give another character more spotlight? Maybe it’s her slow growth that makes him more interesting and vibrant? I’d love to hear your strategies.
