How come you can always disable gay content but never disable straight content?
Just as much as straight people don't want to view gay porn, I don't want to see straight porn but all the games that feature both only let you block gay content. :/
I can't even count how much straight porn I've had to see in games where I made the MC be gay and how (obviously) uncomfortable that made me. Total boner murderer. I've come to a point where I just delete games the second I see that you can only do that and it has noticeably minimized the amount I can comfortably play (lerned that lesson after I played through an earlier update of this game and other 'mixed' games).
Firstly, because straight people are and always will be, the majority of porn consumers. The gay filter is for those who don't want to see gay content, because that content is all optional.
I don't use it, simply because I don't care that it's there, and don't actively seek it.
Secondly, you didn't make any MC "be gay". You've played games where the MC can be straight or Bi, instead of ones that are games featuring only gay content. You being uncomfortable of seeing straight content in any game with optional gay/Bi content, is your own fault for not seeing the obvious.
