I cannot understand why fisting scenes are illegal in this country. Fisting is just sticking a fist inside a cunt or ass, girls can be shown plugging in huge dildos (Amazing Ty for example), but we can´t see a fist ramm tose holes.

Sure you can.Fisting is NOT illegal,in fact I include fisting in the "behind the scenes" of many of my DVD's.Check it out.
