Well, ruudhass,
SOMEONE is having COUNTLESS fun!!!!!
Yes, it's normal. Especially if there are teeth rubbing off microscopic skin layers and some epithelial cells on the glans penis. Also, if you are circumcized, there isn't that nice little skinpouch to tuck the "abused" head into, so it's also exposed; in addition, rubbing and chafing the meatus (urinary opening, full of tender, sensitive nerve endings)against underwear, pubic hair, etc will result in tenderness.

Now I'm not a physician, so if it persists, do visit with the urologist. In the meantime, tell those ladies to keep their fangs tucked in while aspirating. Or better yet, make an appointment with a dentured provider

Please excuse the levity. This was such a cheerful one, in all its sweet agony,
the Love Goddess

countless orgasms?

I'm surprised your balls didn't ache.

Years ago when I was just hitting puberty and found the joys of masturbation, I think the hormones were flooding my blood stream.
I decided to see how many times I could cum in an hour.
I got to 6 in 60 minutes and my balls ached for 3 days. Felt like some field goal kicker hit me in the balls.

If you came countless times, your plumbing should be sore....especially when it's overused in a short period of time.

take some advil
[with food, otherwise it will upset your stomach] to lower the inflamation/soreness.
And I'd drink some cranberry juice, just to clean the pipe out too.
and next time, drink pineapple juice or pills for your provider and your wife.

I've had it happen twice in a 7 year itch of hobbying (once I started scratching I couldn't quit, but that's a different thread).

My feeling is that it was the agressive suction (some of these providers don't know their own strength) and not the girls fangs that did the damage. In each case it took me two weeks to recuperate and besides drinking fluids as suggested, I'd advise rest and relaxation until the ringing subsides. You've got a sensitive organ and if you put it in harms way again, until it's fully healed, then you desrerve more pain and suffering. Take it from and idiot that knows-what-the-fuck and rarely ever listens to his own advice...and has paid the price.
