1. Raene
is a girl, she just happens to have been born with a penis. It's heavily implied that she is working towards changing that, but there's no guarantee.
2. Speaking of, if you mean to ask "does she ever transition to having a vagina, during the course of the game," probably not, as has been said already.
3. Not judging you if you Do Not Want. I don't get off on it either, tbh. Not wild about the futa LI either. But I appreciate both of them as characters.
4. They still have stories attached that might be worth experiencing even if the porn doesn't do it for you (or me).
5. It is BEYOND okay for there to be LIs in a game that I don't personally find titillating. I don't need to be the core audience for every piece of content I consume, and in fact it is better for me as a human being if I am not. People with kinks I don't like deserve to get off just as much as I do.
6. At the end of the day, it is your choice whether you're curious enough about Raene's story to rush through the lewd scenes and ignore the turnoff, or not. And whatever you choose is okay! If you're turned off enough to skip interacting with Raene, that's totally fine! That's the whole point of having choice! But don't be a dick (word choice very much intended

) about it. The dev doesn't owe you a story without anything to challenge your world view.
6a. I don't mean to imply that there was anything wrong with you asking a simple question, or that I found you especially whiny. There wasn't, and I didn't. It's just that most people who ask that question are also dicks. Please don't be that guy. That guy sucks.
