Multiple multiples

My partner and I have been together for nearly 3 years. The sex has always been great and progressively become better. She is much younger than me. I am 40, her 24.
We have sex everyday at least once and she always has multiple orgasms most of which through penetration. This will probably sound like bullshit but it’s not. Yesterday over the course of about 16 hours, we had many hours of amazing sex. She had 38 orgasms through penetration and I had 9. I was just wondering if this is common or what not as in my past relationships neither of us have ever had anything like these numbers.
