This may sound strange and stupid all at the same time, but I had unprotected sex/oral last weekend and I think im allergic to something that he had in his mouth prior to engaging in oral. I have had a severe allergy before to tide powder detergent and was told by a dr that it was due to the saw dust they fluff it with. I swear im allergic to everything under sun. Is it possible, him being a cannabis user, that im allergic to what he smoked prior to oral? Im very red, and itchy, but not like a yeast infection itchy/red...suggestions?
