So my male ball python seems to be acting weird and I honestly am trying to figure out if its a multiple of things or if there is something wrong.

First I thought he had RI because he yawned or opened his mouth a few times. He hissed a couple times recently while in his water bowl then when he was moving around the edges of his enclosure. I thought at first he was maybe shedding? he was rubbing his head on the walls of his enclosure and "yawning." but he hasn't shed yet. Then a couple days later (today) he was in his bowl and i heard him hiss a bit. I read hissing could be a sign of RI. I looked around his nose etc and saw no mucus. Now he is outside of his water bowl and is puffin up a bit and i swear i saw his hemipens come out randomely a few times. and he is in a ball with his head up and his tail was up for a bit and now its down and hes still puffed up. But he sometimes slightly opens his mouth and is just sitting there. But he doesn't seem to keep his mouth open. He just slightly opens it sometimes. Just seems strange! Not sure if there is something wrong, or if he is thinking about breeding and before he was just going to shed or what is going on. Just want him to be ok haha. I looked for a good vet in my area and can't find one.
