yeast

Hello,
I am a girl of 26 years. It is 10 months i am living in a deperate situation. Last year in december i had my first time sexual intercourse, and neevr had it after. But from january i am having yeast infection. It all began with burning in the vagina, continuing burning and sometimes itching. It burned so much that i felt to cry when the urine touches the place. I am still in the same condition even now after 1o months. Continuing burnings and itchings. I dont have a UTI and never had, do not have chlamydia or this stuff. The doctor said yeast infection and gave me 3 ovulas of gyno pevaryl. They did nothing. I want to ask why after the first time sex? Is it normal to get this? Is there a cure to get rid of this miserable condition for ever?
thank you very much
