the only dating games about men that i've found are either yandere games or about just regular human men and I just can't find many i like other than 3 original yandere games and one singular fangame. So I'd appreciate some suggestions or ideas on how to sort through games.

There are a few ways to find them!

If you're into men dating other men, you can find games using these tags (I noticed you mentioned you don't want to play any AI generated games):

Boys Love + No AI (/games/tag-boys-love/tag-no-ai)

Yaoi + No AI (/games/tag-no-ai/tag-yaoi)

Gay + No AI (/games/tag-gay/tag-no-ai)

BL + No AI (/games/tag-bl/tag-no-ai)

If you're looking for women dating men in dating games:

Otome + No AI (/games/tag-no-ai/tag-otome)

If the main character is the player and has no specific gender (and the people you can choose to date also usually has both genders available):

Amare + No AI (/games/tag-amare/tag-no-ai)

Or generally all dating sims without AI:

Dating Sim + No AI (/games/tag-dating-sim/tag-no-ai)

Hope that helps~ People tag their games differently, so sometimes you gotta trawl a little bit haha

Yes, you can find dating games with men by using tags and filter category combinations. You can try
Otome + Dating Sim 
GxB 
Female Protagonist + Dating Sim
Dating Sim + Gay
And so on as long as you're specific about what you're looking for.
