That's fine and all, but everything you said is irrelevant to my point though. It doesn't matter what you've done IRL, and it doesn't matter what I would do IRL.
I chose to not have sex with Michael, the reasoning behind my decision is not important. What's important, is that my decision caused the game to force a character (David) on me who I had already rejected, which is an inherent flaw in the game itself and trying to justify it through real life experiences doesn't change that fact.
In a choice driven AVN, you should never get a character forced on you if you were previously given (and made) the choice to reject that character. If the game is just going to ignore the fact that you're clearly not interested in a character, then why present us with the option to reject them in the first place?
You were the one who said "One assumes this will eventually lead to Victoria having sex with other guys", which is what I responded to. My point was that there's no need for that scene to lead to that, because that has already been happening for some time at that point in the game.
As far as the scene itself goes, no matter how logical it may seem to you, this is still a game based around the choices the player makes. There is absolutely no reason why that scene needed to be unavoidable, and that's all there is to it. It takes away a ton of player agency which happens to be why a lot of us (probably even most of us) play this type of game instead of kinetic novels.
The reason I object to it is because Lucas is an incredibly unlikable character, and when I finally thought to be rid of him he suddenly shows up and we're hit with one of the most cringy sex scenes between the MC and her doormat of a "boyfriend" I've ever seen in an AVN. It literally adds nothing of value to the game, and I'm sure plenty of people feel that way. Even though the scene wasn't forced on Victoria, it was forced on us, the players..
The biggest problem isn't even that that scene is in the game, the biggest problem is the fact that we don't get the option to avoid it. I could repeat what I said about this being a choice driven game and all that but I think you probably get my point by now.
I could ask you the same thing by the way.. Why do you object so strongly to me wanting an option to avoid certain sex scenes in a choice driven AVN? Why do you feel the need to justify bad design choices by applying your own real life experiences to any of the issues I've brought up? Such a question really goes both ways, as you can see.
