Poor Jay! It's extremely serious that he has a swollen penis, and if it's purple in color, I would be concerned that the blood supply is reduced to his penis. It's also not normal that he is urinating in the house often, and that could be caused by a UTI or bladder stones. I would have Jay seen by a vet immediately so that his symptoms can be diagnosed and treated.
