Whats wrong with my kickflips's?

you not flicking right.its actually your pop though. your just popping it but not flicking. and when you pop and dont swipe, your board goes up and WHAM!str8 in the crotch. so what you need to do is you need to pop and swipe. dont just pop as hard as you can and you cant keep up wit it with your flick. pop moderately and just flick with it. make sure you got a strong and decent ollie.
