I said this many times but when i first pick jungle and i dont have the jungle im out of options

i fist pick jungle every game and pardon my existance as an only jungler but i just want to jungle and not midlane or toplane. im not able to get the jungle game and its really dragging the game for me. ill log on the game once every 5 days and see if i can first piock jungle but i dont get the jungle....................
