Seems like it's more of a one off incident to me. He probably got caught up in the moment and in his passion. Perhaps express to him how you felt about it and that it caused you discomfort. He may just need to be made aware and you bringing it up may make him more mindful. It seems otherwise, he has been great, so perhaps just address it and trust the remainder of your assessment. If it keeps happening, that's a different story. ((((hugs)))))
