He is definitely vocal, he is always puffing and huffing... But he really does not mind his head being touched whatsoever, I mean zero response to his head being touched, you can really get in there and rub his head, he even lets me pull his lips back by hand and remove any substrate he may have gotten stuck in there, but he hates his tail bein touched, that always guarantees a big hiss and he will pull his tail away and tuck it under himself.
I dont think he is musking as their is no fluid that leaks out, I really think it might just be a fart, as he is a little constipated, he is overdue for a poop. I have even heard him rip a fart once while he was just sitting there in his water ( I have also seen my ball python do this as well ) I have definitely been musked on before by hognoses and kingsnakes and numerous other snakes.
The past couple of days he seems to have been in a much more receptive mood when it comes to being removed from his tub, he even let me put him back with no problem. I have started putting him back by just opening his tub and putting his head near the open container, he then will almost always just slowly slither his own way into his hide, this is much better than trying to place him in there!
