Im a 13 year old boy and i get random boners and i get horny a lot is this normal and can it stop?

Hi i was watching tv and i got a random ***** like i always do so i left it alone. After 10 minutes later i started to get a horny feeling and i had a sudden urge to jack off or touch myself down there is this normal for a boy to go through puberty? And is there anything that can stop theses encounters?
