I don't really see the appeal. If I want to just see sex scenes I would watch gonzo porn. Vn's and other story driven (game) media have an appeal to me because I can engross myself into a story and play like I actually am one of the characters, but if I'm playing as a character I don't enjoy playing as then I won't enjoy the game. (like for example a cuck)
I also don't want/need all women to be potential LI's in games, as I prefer single LI focus romance games or silly porn games sometimes, like power vacuum or sexbot. But just like my female friends in real life, I don't want to see them fuck in game either.
I also don't really get limiting the enjoyment of romance to irl relationships, I mean I enjoy going out with my wife but that doesn't mean I can't also enjoy romance based games, hell sometimes I play them together with my SO.
