NEED ADVICE/OPINIONS

My husband was at work and a female coworker asked if she could feel his face because he had shaved, he said yes, she did and then she kissed his cheek. He says he immediately corrected her and she apologized saying it was innocent.

I'm pissed! She knows he's married, but I feel like he should have never gave her permission to touch him. Why did she feel comfortable enough to kiss him?
