How big is your new burm?The reason i ask is because if he/she is of any size then dont under any circumstances let it around your face until you get to know the warning signs.Anything above 4 ft can give you a nasty bite around the face area that would possibly be very painful.I had one just miss my face one time and after that unless i know and trust the animal it doesnt go near my face.I've never personally been bit by anything bigger than 2 ft. but one time towards the face was enough for me to learn to read my animals.As for the urinating,i've had them urinate on me accidentally if they had to go but yours seems more of a defensive approach,or maybe you scared the pee out of him/her lol.Handling sessions with a snake hook or without (whichever you feel more comfortable with) will eventually calm him/her down but realize that not all snakes of any kind WILL tame down,some will always be flighty,nervous,or just plain defensive.Hope that helps.
