Lava that erupts underwater and takes the form of round lumps is called pillow lava
I just took my dog to vet for same problem, had him neutered a month ago. vet said it is normal, that it is the part of the penis that swells when mating that causes them to get stuck. Nothing to worry about he said.

Take your dog to the vet. Lumps are never good on any part of the body.
Hamsters get lumps under there bums that are the same as the skin color even if there not male. The bumps are commonly found below the tail.
i think you need to go to a doctor
yes
A big black penis
Painless fatty lumps in the legs are usually due to soft tissue sarcoma. However, to be sure, it is best to schedule an appointment with your doctor ASAP!
It's probably not swollen, when a dog has a full erection his penis will be quite large, often larger than a human's penis. The big lumps at the base of his penis is probably the part called the knot.
