Hello! :)
Thank you for the kind words; I'm happy to hear you're interested in our project.
We don't have any plans to include MMF content, sharing of love interests with other characters, or prostituting your female companions. The game's lewd elements lean towards harem & romance gameplay, so any such content featuring multiple characters will show only your MC with other girls. We definitely plan to add brothels to the game, but again their content will feature your MC sleeping with female courtesans in exchange for gold.
It would be more realistic for a medieval setting to have the type of content you described, but our game is a power fantasy in the vein of 80s pulp comics where the Player Character is the main hero of the story and has little to no competition from other men. Likewise, all the female love interests gravitate towards the MC due to his background (war hero, ladies' man, local celebrity, etc.), so within the context of the story it wouldn't make sense to have them seeking out other guys to sleep with, nor would any of the girls agree to be pimped out to clients for gangbangs.
Hope that answers your questions. If you have any more feel free to ask! :)
