Swollen penis, no fur ring, lethargic

I need advice & help. I CANNOT get to a vet- my partner was recently in a really bad accident and we DO NOT have a car or income right now, as he can’t get to his job down the mountain anymore. We are living off minimal savings right now until we find a job within walking distance. This was the worst possible time for this boy to get sick so here we are, and I am trying my best but figured I would ask for help here to see if anyone had dealt with something similar.

Okay so:

Very long...
