I’m glad you asked. The cut doesn’t make it more likely that you would acquire HSV 2 orally, no. If you were diagnosed last year, and he is also infected with HSV 2, your infection is well established and if I were you, I would take this off my worry list. If by some rare circumstance, you did acquire this orally, it would look just like a cold sore and likely not recur. Enjoy your sexual relationship and try not to be concerned about this.
