I actually feel bad for you, people here seem to have completely misunderstood what you were saying.
I love this IF, it’s by far one of the most promising I’ve followed in the past few years, but I do agree that MC’s characterisation is very feminine, or better put “BL typical”.
If the player choses their MC to be into women, then he shouldn’t act like a fair maiden when touched, kissed, etc. by another man, the average straight dude would feel at least uncomfortable if not outright grossed out. He wouldn’t blush.
I understand why you are upset about the characterisation; the MC was either written with a female MC in mind, or he’s heavily intended to be gay/bi.
While I still love the game, I can totally see why it’s disappointing for someone expecting to be able to play as a genuinely straight man.
But. You have to keep in mind that people on here aren’t professionals, and most IF devs women, it’s hard for layman to write the opposite gender, hell, many professionals can’t even do it.
You have valid criticism and stating it calmly, explaining it properly, might even help the dev to improve – but there’s no point in being rude or raging.
Maybe IFs from the “choice of/hosted games” brand would be better for you, they cater more to straight people, and if you are into superheroes/villains, I highly recommend the "Fallen Hero" series, which does all sexualities exceptionally well.
