Sorry to hear that. I'm actually acquaintances with that guy you talked about. We talked a little and he said that he didn't know what your perspective was. He told me he's willing to talk about potential future content concerning sex scenes with you. If you have a Discord or Twitter feel free to DM me at either @ChellayTiger or ChellayTiger#3120 and I can get you two to talk. Or you could talk through Patreon if that's an option. But yes, I do think he should have labeled the characters' positions beforehand.
Anyways, I'm glad you agreed with my points, especially considering the value some erotic games put on roleplaying as the main character. I think it's important to make sure the player doesn't feel like the game doesn't let them do what they want to do in those cases.
