I just went on the web and read about the procedures you've had done. I'm sorry you've had to have so much discomfort and pain. Were you given a fully informed explanation of the complications and risks of these surgeries? Was the doctor who performed them the same doctor your now going to this week? I'm only asking because I'm sure you were told it was medically necessary and you had no other options,but if you weren't given the information about everything that could happen afterward and this is the same doctor, then by all means find someone else.
Would it be possible for you to find a female gyn? I have always been more comfortable with women Gyns as they are generally more compassionate and willing to listen to any concerns and problems your experiencing. Your doctor should know better than to be so rough with you and it certainly is normal for you to scared to go and see him. Was he the doctor that did your surgery? You need to tell him before the exam that your not comfortable with the way he's been examining you and that if he can't be more considerate of your feelings and physical well being that you would prefer to see someone else. If you saw a female doctor, you might feel more at ease discussing your problem and discussing your concerns about your sexual health. There might be some kind of procedure or treatment that could help this condition. It isn't fair that at 53 you can't be having a healthy physical relationship with your husband.
good luck
