the tassles of my corn are just starting to have the pollen/anthers come out. i was reading in "seed to seed"

about hand pollinating and it was a bit confusing. it sounded like hand pollination was only needed if you were trying to stop two different corns from crossing. i have only like 10 stalks, do i really need to bag my tassles and cut the husks growing out from the sides and then pour the pollen into the silks,

or will nature do all of this for me?

if not, will someone please give me really simple correct instructions on how to do this properly.
