Allergic reaction to semen?

Hey y'all I just am curious, I have an allergy to cinnamon and recently my boyfriend has ate items with cinnamon during the day and then later in the evening we have sex and he ejaculates. The next morning I an broke out in a rash on my chest and back and arms and very itchy similar to that of an allergic reaction. Has any one ever experienced this or know if it's possible for an allergic reaction to happen because of this. TIA!
