The thing is, U can do just about ANYTHING with 2D. But there are limits to what can happen in real 3D(unless its animated of course XD). BUT 3D chicks are real and 2D chicks arent....BUUT 2D chicks are most of the time hotter than real 3D chicks! oh my head! @_@?!
In terms of the following presented pics
definitely choose 2d only since 3d never fully as cute as 2d
exceptions are like the girls in the Death Note Movie
And if you think 'bout it 2d girls are orignally based on 3d
I'm being real right now so ill go with 3d because you cant have sex with 2d girls only fap while watching them but if I could live in the marvelous world of anime I would choose a 2d girl
