Sorry if i sound rude, but this is like saying "ermmm what if the male MC dominate the women instead! i prefer straight and consensual reproduction!" in the tower of trample thread, it just doesn't make sense. Also true open world in a porn game is VERY rare, removing that open world part of your filter will give you a lot more selection of games.
Maybe people dont like seeing guys riding a dildo and dancing on stripper pole? like the things you can do in this game?
Also if you want a dude MC getting a harem, try going to steam. A lot of "straightconsensual slop" are there already and no sane human being go down here asking for your average anime plot as a game.
For the game:
Aside from the janky shooter section, its pretty good. I love how you can still "cheese" the progression by just fucking the leaning girl on the right side from the house upgrade lovepoint speed then repeat.
Extra penis option would be great! both "extra penis" option and "extra" penis option.
And maybe more monster girl stuffs
