Anyone familiar with the specifics of the japanese gun law concerning the question on if shotguns are easier to obtain than rifles and if there is a limit on how many firearms can be acquired?
(possible origin of the oddball option of using a scoped shotgun)

It's more Evolutionary psychology than reading too much Yuri.
From a practical perspective assuming the relationship is not terminated:
The worst-case scenario of a women cheating with a women is deception and decreased affection ...
If it's with a man the worst outcome is you...
Fiction is indented to provide something you're unlikely the experience in real life, you identifying with the protagonist.
Financially providing for a slut on the other hand is a scenario easily attainable to anyone with a decent income.

It's probably a common type of OCD but not necessarily germophobia.
The brain regions for disgust (of physical dirt) and hate are more or less identical, so the feelings short-circuiting and having the urge to wash your hands after shaking hands with someone you dislike is fairly common...
