Thank you, I worked hard on it.
Well, to really spot the issues with those 3 points, starting from the last, any game where you "create the main character" is automatically a game where you self insert into (not by choice but by design, and not necesarilly completely), the choices you make are yours and those are part of your input, your expreience, your own interation. If I wanted to feel disconnected I would just watch porn instead of playing porn games. It's not like I imagine myself as the protagonist of a game (I don't have magic/sword skills and I don't go around beating people up) and I think it's the same for most sane people who play this game, I just personally enjoy seeing the scenes that are nice and wholesome mostly, cause even Cait has those if you sex her. The actual problem is many scenes where you "click to cuck" aren't directly labeled as such, nor disclaimered nor anything (and I mentioned Cait specifically because she is involved in the vast majority of them). They always lead me to read a few lines, going "oh so taking these options means getting cucked" and then reloading save. That's my point of view, hope I didn't offend you in any way.
Edit: Also just wanted to clearly express that you don't need a relationship to be cucked. Even irl people with one sided feelings can be cucked. Hope this helps.
