Hi, i been a the doctor 7 times in the past year and I have had problems with my genital. I am an 18 year old female, and now for a very long time, I have not been able to have sex, because it burns. I have been tested for STDs, and all were negative. My doctor says that I do not have fungus,so I do not, know what it is, and my doctor is not very helpful, she gave me a prescription for ph stabilizer, but i already tried that. she wont give me access to the gynecologist. what can it be? my symtomes are: burns while having sex, and sometimes it is itchy, but not very often.
