Breath rate lever man versus smaller woman?

I have trouble sleeping with a new person in bed so matching my partner's breath is a method I use to put myself to sleep.

The he other night when I did this I noticed the guy I'm seeing breathes a lot faster than me. He is a foot and at least 100 lbs taller. I'm thinking it is because he is out of shape. He says he runs a couple of miles 2-3 times a week but he has a bit of a gut and gets out of breath in bed. I've been running for 3 years, swim and had formal training in singing young so I have maybe a little above average control of my breath.

should I be concerned? Shouldn't he breath slower than me assuming we were in equal shape given our size difference?

I really like him and I don't mind the weight but for an LTR I do want my partner to have healthy CBC and what not.
