There's many ppl would want this change; just look at steam and the forum.
A lot of people have also asked for Cait pregnancy and for Ryn to be given a vagina no matter how many times Savin has said that neither is happening. Just because an arbitrary number of people want something doesn't mean that it's feasible or that they're going to get it.
I don't know, I'm not a coder but having something in the Parsers work with them as Perks and act like keys should work and not be too hard, eg:
PC selects at start > Homoerotic Perk (allows for same sex scenes, because every Npcs sex is kept track off, we all know this)
At this point you run into all of those edge cases that Drake mentions as well as running into the fact that the game just isn't
written that way. For example, lets say there's a 'heterosexual' tag and the Champ is male. Does that tag then only proc scenes for NPCs who have a vagina and no penis? What about females with a penis and no vagina, or with both? Because either way you're going to run into people who will complain that they've either been locked out of content they wanted to see or were 'made' to see scenes with ew penis and they didn't like that. Homosexual tag and the Champ is female, same thing. Apply as needed to all other cases. How about the degree to which an NPC is furry and filtering based on that? You'd need lots of interlocking tags to cover all the possible angles and that is much
much more work than what the devs for CoC2 and TiTS have said repeatedly: If you're not into it,
don't click on it. Y'know, like Drake said in that post; The needs of a vocal minority of people who don't want to see X is not something the devs are interested in catering to in a deviant porn game.
