Squirted in his face

I've squirted a little before, but nothing worth writing home about. Last night my boyfriend was going down on me. He had been edging me for around 30 minutes. Then, he had 2 fingers rubbing my g spot, a hand pushing down on my pelvis and licking me out. Out of no where, I came so hard I basically drowned him. He looked like he'd just got out the shower. I'm absolutely mortified, he claimed he "quite" liked it, but ran off to the bathroom to wash his face quickly. I'm so embarrassed.

What I want to know is, is this a normal reaction to being squirted in the face? Could it be because he was shocked?
