I haven't played yet but I got so excited until I saw this comment. Please spare us since you made Ikki a top, I'm tired of everyone fetishizing trans men's bodies, especially since we barely get any inclusive works at all. :')
there are plenty of trans people who find it affirming to see a character who reflects them, and yes that can include their genitals. personally I love to see a pre-op trans man still treated as a man in the bedroom. if that's not you that's okay, but it doesn't mean that it's automatically bad or wrong to include.
regardless, the current build of the game doesn't place emphasis on ikki's genitalia in the bedroom.
