Oh Jeanne, you really should have had that seen to (and still should if it's
not healing well).  When Bandit bit me in my knuckle I "bled" the wound for
as long as I could, washed it out with peroxide, called my doctor
immediately and got him to call in some Clavamox to start taking right away,
and then went the next day to have a tetanus shot.  And it *still* took a
long while to heal.  The doctor said that the only bite worse than a cat's
is a human's.

From my experience semi-feral cats no matter how long you have had them are
always just that when they get fed up about something.
I was glad that the vet gave Kitty FC a long-acting antibiotic injection
after she was ill/injured last year and luckily it worked.  I cannot imagine
how I could ever pill her even though she is small in comparison with your
lad.  Even grooming her (and whew, I recently did it so she looks quite
smart) is fraught with ouchies.
Boyfriend, OTOH, would be a different problem if I had to pill him.  He
would be terrified to be held firmly and I might lose all the trust we have
gained.
I can only hope they both remain well.
Adopting feral or semi-feral cats can be challenging at times.
I once took KFC to the vets (earmites) in a cardboard cat carrier which had
holes in it for breathers.  A 6 mile drive.  She lost no time in objecting.
After a mile or so, she had her claws through the breathing holes and was
ripping at them.
I drove faster.  More ripping noises and a bigger hole appeared with KFC's
eye peering through.   I drove even faster.  I didn't want to be alone in
the car when she burst out ;-)
We just got there in time.  I got her on to the vet's table and she rose out
of the box with wide eyes like saucers and ready to kill.
"I think you might like to get a vet nurse to help you" I said.

Jeanne, please see a doctor about this.  Cat bites and deep scratches
from a cat's claws are nothing to fool with.  My daughter, who by the
way is a registered nurse who should have known better, had some cat
bites and scratches get infected because she put off going to the
doctor about them.  It wouldn't have cost her nearly as much if she
had gone right away.

Hugs and Purrs

Ouch! Sounds bad. I hope you're right and it will heal by itself. Poor
Hobo. With my five injections a day, tell him I understand how he feels.
Like a feline pin cushion.

Lots of healing purrs and best wishes for you, Jeanne,
