how many times does a guy cum a day ?

Like... a guy you've been with for a few years and you live together?
For me it's like, I can fuck 5 times a day and I'll still want more, even after all this time. 
But my guy isn't the same. He has sex once a day...every few days... sex is short and uneventful. 
So, based on that, is this normal? How many times does your guy cum or want to cum a day?
