are genders fixed or will there be male, female and others as options
Player gender is fixed, just because I would have to make alternate sprites for every player animation and grab animation otherwise. I would do it if it didn't create such a large amount of extra work.
could use layering to add either breasts and vagina or a cock and balls, otherwise the body shape can stay the same between the two
Yes, but I'd still have to animate them to match each player animation and grab, which isn't any better.
