I've been bit by every snake I've owned at one point in its life. The only exception is Dottie has never bit me but I have to be extra careful with her at feeding time as she has a stronger feed mode than a darn retic You get used it, it doesn't hurt unless its from a big guy. Then you bleed some, cuss some and the snake stares at you. Key is don't yank away if you get tagged or it will make it worse.
And even in the heat of the moment, take your snakes safety into consideration. (ie, don't throw her across the room). No matter what happens you will be hurt less than your snake.
