It's always a struggle writing masculine male characters for me. The stereotypical macho man or stoic strong silent type, I have to write them the same way you'd write an orc or goblin or some other fantasy creature. I know guys like that exist, I've met them. I just can't get in their heads and write them with the same personhood I feel naturally when writing female characters. It's easier to write them as static characters than dynamic people.
and that's hitting the nail squarely on the head.
Look at it this way.
Take "gender" out of the equation entirely, and replace it with something else entirely you have no experience with.
Say... a factory that builds passenger jets for airlines.
Where would you even begin?
---how does a plane even stay up in the air
---how are planes built
---what are passenger plane factories even like
yet... Michael Crichton wrote "Airframe".
He also wrote "Jurassic Park"
He also wrote "Eaters of the Dead"
He also wrote "Andromeda Strain" (his first novel he published under his own name)
His novels are known to contain a *lot* of technical information around the core subject.
He obviously does a lot of reading and studying to create a realistic world.
Now... remove the technical substitute subject... and re-insert the opposite gender.
See the problem?
Its no different than...
your novel will be all about something happening in the world of... Electrical Engineering work.
but you've never held a soldering iron in your hand.
you don't know a resistor from a capacitor from a coil, nor even what these things do.
how would you *solve* this issue? Easier said than done...
you'd have to learn about Electronics.
PRO TIP:
TikTok short video clips, and "click-bait" articles...
are probably not going to give you what you want (need).
