I am 24 yrs old old and for almost 2 years now I have recurrent yeast or bacteria infections after I have protected sex. I am not in a relationship but I try and stick with the same person for as long as it lasts. I protect myself everytime but it NEVER fails I always end up with yeast of bacteria infections. I want to know what is the cause? Am I allergic to the condoms, I mean I just don't understand. I've tried to douche with vinegar and water right after sex and also I've taken Diflucan once a week or once after I've had sex and NOTHING helps. I need a resolution to this problem. This is making me very depressed and I feel like my love life is over because of it. PLEASE HELP ME.
