I am allergic to some common condom ingredient, but haven t determined which one yet. It isn t latex, and it isn t N-9, based on the fact that I have the same painful allergic reaction to Skyn condoms (Lifestyles product), which are non-latex condoms without spermicide. My symptoms include redness, itchiness, dryness and lesions of the labia. Symptoms appeared within an hour of product use during sexual contact. What else in condoms might I be allergic to?
