vaginapagina | Vaginal Dryness/Burning sensation

This is a bit of embarassing question. Off and on I will go through periods where sex is very painful. It is almost like I have an yeast infection, but I know it isn't cause I've tried treatments and such. We don't use condoms as a form of birth control so I know it is not a latex allergy. Recently this has started again. I will feel extreme pain in certain positions while having sex in the cervical area, and the outside is burning and itchy. It almost feels like there are little open cuts, and it is really painful. This is really depressing me, and how I've been responding to my boyfriend lately. I don't want anything to do with sex, and I just feel hurt and disapointed that I am not able to give that kind of intimacy to him. He seems understanding, but I feel the definite strain on our relationship because of this, because I feel really depressed of the situation.
I am at loss, and know I should probably go to my Dr., she is the type of person though who likes to just push pills at you. Any suggestions as to what this might be, cause this is getting really difficult to deal with:(.
