Im in a band, and i exhale, i think i sound pretty good, im only 13, but i sound great, i think, sometimes you have to be a natural born screamer, my voice doesnt hurt after a scream

what i do is---
1.i do the oooohhhhhh YEAH! from the beginning from psychosocial from slipknot
2.I start to say random things
3.once my voice gets used to it i can scream for a very long time
4.Record, although it does take time to get the screams perfect xD
5.Get a bunch of air before you scream, like breathing exercises
6.DRINK WATER EVERY ONCE OF A WHILE!!
7.Scream the way you like, im not telling you how you feel when you scream, just tips
Thats about it, good luck!
Plz watch my video on youtube!!
