"The point is not just a matter of ready or not ready and stimulated or not stimulated alone. If she was ready and excited, definitely not going to hurt," said Specialist andrology and sexologists, Prof. Dr. Dr. Wimpie Pangkahila, SpAnd, FAACS in his writings in the quoted detikHealth Friday (29/04/2011).

When a woman aroused the blood stream will flow quickly and smoothly. This condition causes the blood vessels widen, including in the vagina. Widening is what determines whether or not the hymen tense.
"It was nice not sick or do not bleed. Women may not bleed during penetration and her hymen was torn, because it means the man was able to stimulate women well," explained the doctor who earned his sexologists from the University of Washington, the United States is .
The same thing also disclosed Dr Andrew Wanananda, MD in his consultations in detikHealth said that the bleeding on the first night of sex depends on the elasticity of the hymen, if the bleeding does not occur very elastic.
