Since My Husband Started Taking Suboxone, His Semen Burns Me.

Since my husband started taking suboxone, his semen burns me. He pulls out.?we thought it was a protein allergy, thats been ruled out. I was Just recently diagnosed w an acute autoimmune disease, w/ vulvar presentation. The literature shows autoimmune disease caused by suboxone. Could chronic burning from his semen elicit an immune response to suboxone in his semen?
