I have a allergies to wheat, rice, oat and other foods. My usual symptoms if I ingest these grains is diarhea, excema, headaches, and other symptoms depending on what I have consumed. Now having stated that I have noticed sometimes, not all the time, but sometimes I experience diarhea after oral sex and swallowing my husbands semen. I am wondering if it is because he has consumed some of the foods I am allergic to. Could this be the case?
