Whether your marshmallow wand has stray hairs or not is probably down to heritage/how hairy you are in general. But I agree with
@Poonocchio - a stray hair or two along the shaft, particularly closer to the base, seems common enough. He probably has a really small marshmallow wand so it's imperative to use every single bit of it. I'm actually amazed he has the patience and forethought to get the hairs taken care of - lots of AGPs seem to love speed-running the crotch bellybutton and take the "I'll deal with that later!" approach (or buy into tranny propaganda that their body will magically transform those tissues and are genuinely shocked about the hair)
