Has Anyone heard of being allergic to Semen?

Question Ladies?!! So I know it's kinda of an odd question but has anyone else experienced some type of burning sensation after husband/boyfriend cums? 
My husband and I are hoping to start a family after 12years being together
And only being married 2yrs and we thought it was a good idea of trying to conceive. So this year we decided to not use any condoms and right after he finishes I immediately start feeling like a burning sensation. 
This usually last for about 15-20min  but still it's very uncomfortable feeling. 
I know we both are STD free so we are good on that part. But has anyone else experience this before?!! 
Is it really possible to have an allergic reaction to semen?
