That is very natural. Last time I went to a GYNO I had a biopsy--it was the scariest thing I've ever been through. I do not go to doctors or take pills anymore, I do not trust any of them. (Read the Ask Barefoot Herbalist Forum for more) I don't think the OBGYN could help you with your problem anyway. If I were you I'd lay off the sex. It's unfortunate in that contract that a woman is obligated to take care of her husband's sexual urges.
We all need to live right and eat right and take care of ourselves--self applied prevention.
My mother has always been poor and never goes to the doctor. I always say that woman is going to live forever.
