It defo looks more like hermipenes rather than rectal, it’s almost as though they are growing on the outside. I have had a snake with rectal prolapse before (not a ball python).
He is on wet paper anyway as he hasn’t had his first shed so I’m keeping him moist. I have been bathing him in sugar water and keeping his prolapse damp. He seems fine in himself but I guess it’s hard to tell if a snake is suffering or not.
