What does a healthy neutered male dog look like in the genital area? Does this sound normal?

My 10 month old puppy had a neuter done yesterday. Due to excessive licking post op while being held at the clinic, our vet put a cone on his head to avoid further licking.

Today I had a look at the genital area (4pm now) and it looks really red where the stitches are. He also appears to have a tiny bright red piece protruding from his penis (not the entire “lipstick” just the tip).

Is this normal? Should I be concerned and bring him in?

I have a follow up appointment tomorrow morning. Am I being overprotective and worrying about nothing?
