How big a man's penis can a woman's private parts accommodate?

My girlfriend and I got married not long ago. On the wedding night, she had pain. Is it because of incompatibility? Is there any standard for matching female vagina with male penis?

The average size of the vagina from the opening to the cervix is ​​about 7.5 cm, but during sexual intercourse, its capacity is flexible and can accommodate penises of any size. The area inside the vagina about two-thirds of the length of the vagina from the vaginal opening is much more sensitive than the front end of the vagina. Although not all women have a G-spot, for those who do, it is usually located on the front wall of the vagina, about 3 cm away from the vaginal opening. Generally speaking, the tip of the clitoris has more peripheral nerves like the glans of the penis. The size of the clitoris is about 0.16 cm wide and 0.16 cm long. Prolonged sexual activity will keep the vagina elastic, allowing the vagina to enjoy this kind of sexual activity for a lifetime. The pain that women experience on their wedding night is mostly caused by psychological tension, lack of experience and other factors, and usually has no direct relationship with the organ itself. Finally, let's answer the question of whether the vagina and penis can match each other in detail:

Regarding the relationship between the female vulva structure and sexual life, there was a special report recently, which concluded that the female vulva structure has little to do with female sexual function. Female sexual function is mainly determined by psychological factors rather than by physiological structure. The question of whether the female vagina can match the male penis. It is also a concern of many unmarried women. Normally, a woman's vagina is 7-12 centimeters long and wide enough to accommodate two fingers. The vaginal wall has many horizontal wrinkles and is highly stretchable and elastic. When excited, the depth of the vagina increases by one third and the width also increases, so there is generally no organ mismatch. We often see a tall husband with a petite wife, and their sex life is just as harmonious; people of many different races in the world can also get married and have children; when a woman gives birth, the fetal head with a diameter of up to ten centimeters can pass through the vagina. All these can make us imagine how accommodating the female vagina is, so your worries in this regard are completely unnecessary.

The vagina will grow larger as sexual desire increases. The vaginal walls are like a pleated skirt, and when you become sexually aroused, these pleats open up, increasing the diameter of the vagina to 2 or even 3 inches. At the same time, the vagina will stretch up to 6 inches. If "he" is not big enough, the vagina can automatically adjust its size to ensure you get the most comfortable enjoyment. Having a baby can increase her size fivefold; normally, our vaginas are no more than an inch in diameter. But before the baby is born, the vagina expands incredibly wide to 4 to 5 inches to allow the baby's head to pass through. But don't panic; within six weeks after giving birth, your vagina will (or almost will) return to its pre-pregnancy size.
