im definitely of the opinion that every, or most, tags/fetishes should be optional. personally i dislike femdom, but ive gone with it for a few chars in other games because i really like the girl. though, i really hope that if there is femdom with Emily, that it is otption as she my fav behind the gf.
I'm not a fan of femdom either, but there have been a few games I've played here where I got to the scene and thought "Is this what they mean by femdom? This isn't a big deal."
I think seeing femdom freaks many of us out because we expect the whole dialed-to-11 thing many visual novels do. So, full out humiliation, pegging, ball crushing level stuff. The real hard dom stuff. But in reality, even games with femdom tags, unless that's the focus of the game, they rarely go that far, and tend to stay in the "I can still enjoy this" range.
I don't see any characters having a real "hard dom" streak. The (planned an only potential femdom scene, open to change based on the devs whims) could be as simple as deciding it could be fun to let Emily have some control over, say, how you and another of the girls have sex while she watches.
Not only is the content likely to be avoidable, but even if not, these are all people who are genuine friends with each other, so I expect the femdom content to be in line with just how they choose to have fun once or a few times, and not a total power dynamic shift in their friendship and relationship.
Also, femdom might not even involve the MC, but could be girls with each other. That's usually lesdom, but I've seen the tags used interchangeably.
One thing I've learned is to be wary of tags, but not be too worried, if I'm otherwise interested in a game, until I see it in context. I mean... I don't like anal sex. I have a strong aversion to it. Not only is it in most every game, it's also almost never avoidable.
So, I shrug and play through the scene, and hope the next one is more my taste. If femdom comes into play, that doesn't mean it will define the character who takes on that role, or constitute the majority of the scenes. My kind suggestion would be, if the scene is unavoidable while on the path to pursue a certain character, and you decide it goes past your personal tastes, to play it like I play anal scenes: click through it, and when it's done, go back to the story, knowing most content is more your speed anyhow and it's unlikely this one scene will alter the remaining interactions between the MC and whoever it is.
