Also I kind of just realized that Eva seems to have a strong opinion on how often women really love to feel dominated during sex even if they don't really give that vibe before the fact. It came to me with Emma's scenes but it is a predominant theme on Lena's story and something also shared by Cherry, Alison and Louise. So far only Holly and Cindy are not clearly showing this and in Holly's case it feels more related to her almost being a virgin, while it seems pretty likely that Axel will show us that Cindy also really likes it despite appearances.
Now, I'm not complaining as even if I'm not into BDSM myself is also a kink I share women being made submissive during sex by a strong man. But while I don't think that women loving it is that uncommon, I also don't think that all women love it (secretly or openly).
Women are people, people are varied, putting anyone into boxes generalising them as a whole is always wrong.
Now, when it comes to porn I would assume that it's a safe bet to go for portrayals of submissive women, regardless of how different we are it's just a fact that society has historically put emphasis on submissive traits for women and therefore if they do not express these traits it is often conflated with emasculation of the male partner.
Obviously that is silly on the surface of things, but I do not fault the makers of porn for following these norms. They are selling sex as a product and you make the product that the most people would want.
Ian can still be on the cuck route and Ivy seems like she would be a less submissive partner when we finally get around to her content with Ian, so the opposite isn't completely absent from the game.
