What Causes Recurring Yeast Infections And Itching On Using Condom?

Hi, may I answer your health queries right now ? Please type your query My boyfriend and I have been together for almost 4 years, first we never used protection and everything was ok, but i decided it will be best to start using condoms and since then i have been having infections (yeast) and other problems such as itching and i have been going to the doctor constantly (almost every 2-3 month)asking them why do i keep getting these when we use protection and are faithful but no answer. my boyfriend did countless amount of test for everything such as trich, syphilis, bacteria, viruses etc and all is well, is it possible that i am allergic to condoms? what are my options i do not like pills or injection?p.s. this is really private, thanks for your advice, can u email me your response as the cable isn't working so well.
