It would be unusual I think for facial hair, as in soft flowing beard, to cause vaginal irritation. Rough stubble of course is another thing. I suppose the answer to your question is it depends on what type of facial hair you are talking about. Also, if you skip oral sex for a while and your vaginal irritation goes away, well that should answer your question.
