Male goblin actually has wider hips and a bigger ass I think.the female goblin does have a bulge, its just a reskin of the male goblin (with different hair)
and I think there is only (2?) correct me if im wrong, characters referenced as having both female and male gentials(Naga, and mermaid?)
so technically speaking theres more females, than 'futa' in the game =P
the rest are just straight up big dick n boobies =O
