I recently turned 41 and have started having problems with dryness in the vulva leading to painful intercourse. At times it itches and the pain feels like cuts or like needles poking me. At times certain areas will bleed but not necessarily from having intercourse but I think its from the dryness. I have been taking birth control for a while to control heavy menstrual cycles and just recently found out that I am diabetic. I did tell my doctor that I felt occasional irritation and she suggested I use a vinegar and water douche once every 3 months if needed. What do you suggest?
