Ok...
1. Fix the husbandry issues of the heat and humidity what exactly is your setup like? Until that's rectified I'd limit handling to as needed for cleaning.
2. BP's brains are about the size of an English pea, there's not a higher intelligence to them.
3. Don't kiss your snake not only are you 1000x's bigger than him and something like that coming at a headshy animal is scary to them, not to mention your heat signature of your face isn't far off a rats head and you're running a good chance of a classic face tag.
4. The bowel movement you described is urates (pee) snake poop is brown unless the animal is sick in which case if you think he could be take him to a herp vet asap.
5. The "cobra pose" you're describing is what we call periscoping, they all do it.
