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
