Is “beard-burn” a thing?? 🧔🏻

Anytime I let my boyfriend eat me out I experience pain/discomfort afterwards for the next week or so. It almost feels like a “chapped” feeling? I have found that Vaseline has helped to relieve this and heal it a little faster than just dealing with the pain until it goes away on its own.. Does this happen to anyone else? If so, what could I do to make this better? My boyfriend has a pretty nice beard and I’m thinking the friction of it as he is going down on me is causing a “beard-burn” (for lack of a better way to put it) down there. Is this a real thing that any of you other girls struggle with?
