And make it so that the player doesn't respond positively to the appearance of characters he doesn't have sexual interest in.
Yes, that's the additional content we're talking about. That means writing variant text for thousands of words of actual writing, plus the code that supports switching to these variants according to player preferences.
You keep saying that it'd take little time and effort, and that's what I disagree with.
I do agree that we need more tooltip that warn the player about some scenes content, though. Stuff like what fetishes/kinks are at play, that kind of things. It's not really enough to know if there's gonna be anal or oral or vaginal and who's penetrating who or whatever - things like who's domming, daddy/mommy kink, preg fetish, etc. also deserve to have warnings attached to them, imho.
Just thought that two women fucking with a phallic instrument would still mostly appeal to lesbians
I think that there are a few reasons why that's mostly not the case ?
1) Women in general aren't as fascinated with penises as cis men seem to think they are. This goes double for queer women.
2) Most futa pronographic content is designed to appeal to men (emphasis on penetration, pleasure derived from penetration, and phallus, female and futa characters designed to be appealing specifically to a straight male audience, objectification rather than subjectification of the female and futa characters, etc.)
3) Penetration is not the be-all end-all of sex, especially to queer people. Queer people in general view oral and manual sex as on par with penetrative sex, vs straight people who usually mostly see them as foreplay.
I am pretty sure I would in no way shape or form like a majority of what I love in Fen Games would anyone do that to me in reality.
I think this all boils down to the good old "PC as Player Projection" vs "PC as Player
's Action Figure" debate. There's no right way to play, but players who favor the former playstyle will probably have more gripes with the game than the latter.
