This game is good, well written and very nice visually, but it's getting a little bit old with every man except the MC being evil, stupid and/or obnoxious and every woman either being very nice and decent from the get go or shown to be a reedemable victim who really is a good girl deep down.
How about letting the MC have real competition from men who aren't idiotic jerks? And instead of excusing his stealing the girlfriends of other men with "the boyfriends/husbands are stupid assholes who deserve it", how about letting the player choose if between stealing the girlfriends/wifes of decent men or take the moral high ground and deny them? That would also give it the affair/romance more nerve (more lust driven).
Finally, let some women be asshole bitches through and through, they don't all need a sob story so that the hero MC can save them with his magical dick and turn them goody two shoes. Having one such character is fine, having several is not. Once more, the player could then choose if they want the MC to fuck the evil bitches too, or if they want to take the moral high ground.
