Yeah, what gender you choose only pops up in conversation in the beginning and only a little bit. Was hoping for more on that front, but it gets swiftly forgotten about so the story can get to the sandbox style gameplay. I remember the developer saying he only put the male start first to better explain the body transfer stuff in the intro, but I feel that leaving the original gender vague would have sufficed. As it is now, it kind of comes off as jarring when the MC goes from a guy to a girl and is almost immediately ready to spread their legs. But to be fair, the game is more of a detective sandbox and less of a character focused visual novel, so the focus is rightly placed on that part of the game. I'm hoping that when the sister gets a new body, it's at least brought up a little bit, but bringing it up when most of the game completely ignores it might not be a good idea.
