Considering that Eva Kiss tries to go for semi-realism here with relatable characters, I highly doubt there will be any kind of transformation happening for Ian or other male characters, unless it's either cosmetic (body build, new clothing, tattoos etc) or a shift in personality. We are not playing as teens who are discovering their sexuality, we are playing in an adult world, and I don't think a 27 years old cis man that never experienced any kind of gender dysphoria can suddenly discover that they're misgendered. And I don't think it will be in good taste to include it and use porn logic to justify it. It's just not that kind of game.
Now, she could potentially include some man on man stuff, since so far we only know that Jeremy and Robert are averse to it, using the word "gay" as a slur. Ian could be bicurious and Perry could be bi in a closet, too. We'll see how Eva decides to develop these characters.
