> who wrote the character that way? The author!

Well. Plus, as a male human, I definitely think some odd thoughts here and there that I don’t see conveyed in a novel.

To your point, the author doesn’t choose to have the protagonist randomly think “Jesus. My taint smells like death today” when said protagonist hasn’t showered in a few days and they’re wearing fabrics that don’t breathe well.

In that case the author is choosing to omit random brain noise that doesn’t add to the story. I’d argue that any chatter about a woman’s bust size could also be omitted as non-pertinent brain noise.
