Looking for games that allow extensive adult activity

[Nirvana_Paradox]

Idk if this sort of post is allowed, or if this is the right place for it. This is my first time posting in General. Hello!

I'm asking for suggestions to games that allow extensive adult activity and adult aesthetics, and kinky things, through modding.
I'm primarily interested in video games with an olden feel. Medieval style games like Skyrim, Conan Exiles, Dungeons & Dragons.
Sci-Fi games that blend fantasy elements are also fair game, as well as modern style games like Fallout 4.

Bethesda's Creation Engine's capabilities are truly a marvel, and I'm wondering if I can get that experience "Elsweyr," however more or less, if you catch my drift. ;)
