Feminisation/sissification covers such a wide range. "I'll dress you up feminine because that's how I get off" is one of my favourites as an arbitrary little thing for the woman to exercise their control. As a major focus going beyond erotic play, I could do without but I'll go along with it if the game is otherwise hot, and it's so commonly paired with a dominant woman (or many) forcing you into it that I might even actively look for such games. Where it becomes a problem for me is when it's paired with forced bi and even then I can tune out some of that if it's, say, in a text-based game and with enough content that I am actively interested in, but some games go hard at making you service cocks and that's where it gets dropped real quick.
