What is a virgin?

1。 In a narrow sense, "virgin" means that women have never had vaginal intercourse, that is, sexual intercourse in which the male penis is directly inserted into the female vagina and sexual intercourse in which the hymen is destroyed due to sexual intercourse. 2。 "Virgin" in a broad sense means that she has never had any sexual behavior, including contact sexual behavior (including vaginal sex, anal sex, oral sex, breast sex, etc. ). Those women with higher morality mean that she has not had any other sexual behaviors with others except the above-mentioned contact sexual behaviors, such as masturbation and kissing for men. The word virgin is often associated with morality. People who maintain a certain moral concept think that virgins represent purity and have high moral value. But in daily life, the basic way to judge whether a virgin is a virgin is to see whether her hymen is complete; However, strenuous exercise such as running, high jumping and riding may also cause damage to the hymen, and the damaged hymen can also be repaired by surgery, so this method can not judge whether it is a virgin in a narrow sense. The "hymen" is unique to human women, which is not available to other female animals. There is a hole in the middle, which is not completely closed. It is a translucent connective tissue diaphragm that completely or partially covers the opening of female vagina. The membrane is pink on both sides, with moist surface, rich vascular tissue and a few nerves. In the center of the hymen, there is a small hole with a diameter of 1-5 cm, which is called "hymen hole" in medicine, and menstruation can be excreted through this small hole. The shape of this small hole varies from person to person. According to the shape of the opening, it can be divided into more than 30 kinds, such as round, oval, ring, sieve, umbrella, lobulated, star, crescent, half moon and lip. The hymen needs to be exposed to the vulva to be observed, and hymen marks are formed after hymen rupture. The thickness of hymen of adult women is about1-2 mm. The first sexual intercourse, hymen rupture to form cracks, and cause bleeding. Due to the different forms of hymen, the degree of rupture will vary greatly. The diaphragm hymen with two holes has more bleeding and more pain. The labia hymen has less bleeding and almost no pain. The thick and elastic umbrella hymen may not rupture at all. The integrity of "hymen" is usually regarded as the proof of unmarried women's chastity, because it usually breaks and bleeds during the first sexual intercourse due to the insertion of male penis, but there are also a few (and very common) tough textures that remain intact after several sexual acts, even after childbirth. With the development of modern medicine, the hymen can also be repaired by surgery, further weakening its integrity to prove whether the first sexual intercourse has taken place.
