No worries: Women and girls may be judged by their happiness, their friendliness, and many other wonderful traits, but not by the condition of their hymens. It makes absolutely no difference whether a person has a big hymen, little hymen, broken hymen, unbroken hymen, etc... One need not and shall not worry about hymens when stretching, exercising, using tampons, using pads, or doing any other activity.
