Why are my male snakes sometimes refusing to eat? Females are eating like champs.

I'm new to the hobby. Please cut me some slack if my questions are off-base or off-target.

I have four house snakes. All young adults. Two females and two males.

My females always eat .. every time. My males are occasionally finicky ... much less reliable eaters compared to the females.

Recently my males began skipping meals ... both of them.

Each snake has its own enclosure, but the enclosures are in close proximity.

Are my males skipping meals because:
They are mostly full grown (their length is a good size for male house snakes) and their eating slows when they are no longer growing much now -- their metabolism has slightly slowed?
Even though it is still quite warm where I live, the snakes feel a change in season?
The males' close proximity to the females has them distracted?
Or all of the above?
Or some other reason?

Because I'm not a seasoned snake enthusiast, I get a little unnerved (perhaps unnecessarily) when my snakes skip meals. The males are eating about every 2 or 3 weeks recently ... small meals.

Thanks for your time.
