anyone's son wait til diaper is off to pee?

I swear he holds it until I undo the diaper and then pees. The first month or so we had a few sprays then barely anything. The last week it seems almost every diaper as soon as it's off I'm sprayed LOL. I said to my husband maybe it's a sign he'll be easy to potty train since he seems to know when the diaper is off it's time to go hah. Any other little dudes doing this to their mama all the time!?!
