as for the technique, try pulling up your pants legs before crouching so they'll stay in place when you're down and your ankles are free and maybe pinch your crotch in your fist, pulling it in front of you, towards your knees and away from your butt as you're down
it's all overeaction at first until you get the jist of it, but it's better to be safe than poop yourself once and live in disgust since and fear your next poop
