I am a man , but I can not relate to having a dick , so it ruins the immersion to me . choosing female makes the game talk about having breasts and being a girl , which I also can't relate to. This is why it would be ideal to be able to mix and match parts , and chose what my character is referred to by ( she or he ) . I hope this helps you understand.
Maybe a potion that lets the player change their genitals , so you could chose the male , change your genitals , and still be the male .
