Talk to your doctor. Think back to the cyst that develops on the ovary during ovulation. The cells in the walls of that cyst are what spur the production of the hormone estrogen. The estrogen level in the body dictates the thickness of the lining of the uterus. A bigger cyst means more estrogen.
More estrogen means a thicker lining, which causes heavier bleeding.
More bleeding often means more discomfort. Nope, not normal. Peyronie's disease usually affects men between the ages of 40 and 60 and can make sexual intercourse difficult, if not impossible. It is not known why the plaques form, but many cases of Peyronie's disappear on their own. Medications are available as well, and surgery can also be used to straighten the penis.
