Thanks for being Paul’s bestie!! The characters assume nothing about the main character’s sex or gender - the pronoun options are strictly for player comfort/immersion and don’t make the gays treat you any differently (they won’t assume you’re a man or woman just because you use he/him or she/her pronouns). Pet names for MC also don’t change depending on pronouns - they’re intentionally gender-neutral (Partner, My Love, Sweetheart, Beloved, etc.). The spicy scenes don’t assume you have any particular set of “tools” either, regardless of which pronouns you pick ;)
P.S. Every main character and most of the side characters are some flavor of trans (as are the devs and target audience <3), so they probably would assume you’re trans until told otherwise!
