处女膜

处女膜的功能是什么？
处女膜没有已知的生物功能。但是，在古代、甚至现代文化中，它被赋予了一些心理社会学的意义。

处女膜的心理社会学意义是什么和曾经是什么？
曾经和现在都有一种观点认为未破裂的处女膜表明了一个女性的童贞，也就是她未有性经历。然而，这种观点只不过是迷信而已。处女膜上通常有1个或数个孔，这个孔可以被伸展，由此没有破裂，也可以承受手指的插入，甚至承受阴茎的插入。另一方面，不仅因性交而且因剧烈的身体运动或体育活动，一些女性的处女膜容易破裂。有一些女性就完全缺乏处女膜。所以，女性的处女膜的状况不能证明任何事情，不能以这样或那样的方式证明女性的性纯洁或性经历。在大多数情况下，首次性交确乎是处女膜破裂的时机，当然，处女膜破裂也能在手淫和爱抚中破裂，或者它也会在妇女首次使用月经止血棉而破裂。

处女膜破裂有危害吗？
处女膜破裂初起可以引起不适和轻度出血。但是，女性没有理由对任何强烈的疼痛感到害怕。在阴道口的两侧、处女膜与小阴唇之间，有前庭大腺，它们相当于男性的尿道球腺。前庭大腺分泌少量的润滑液。然而，性交所需要的大多数润滑液不是由前庭大腺分泌的，而是由阴道壁本身所提供。

 

处女膜的多种形状 女子之间的处女膜不相同。有的处女膜几乎可以完全封闭阴道口，有的可能有数个小孔甚至只有一个大孔。大孔的处女膜似乎是破裂的，而拥有者实际上仍保持着童贞。 Various shapes of the hymen The hymen differs from one woman to another. It may almost totally close the vaginal opening, or it may have several small or even one large hole in it. In the latter case, it may seem broken when it is actually still intact.

 

The External Sex Organs

The Hymen

What is the function of the hymen?
The hymen has no known biological function. However, in some ancient and even modern cultures it was and is given some psychosocial significance.

What was and is the psychosocial significance of the hymen?
There was and is a belief that an unbroken hymen proves a woman's virginity, i.e. her sexual inexperience. However, such a belief is nothing more than a superstition. A hymen usually has one or several holes in it which may be stretchable and thus allow for the insertion of fingers, or even a penis, without tearing. On the other hand, in some women the hymen tears easily, not only as a result of coitus but also because of strenuous physical exercise or sports activities. In some cases, the hymen is even absent altogether. Therefore, the condition of a woman's hymen does not prove anything one way or the other about her sexual innocence or experience. In most cases, the first coitus may very well be the occasion for the breaking of the hymen, but it can, of course, also occur during masturbation and petting, or when the woman first uses menstrual tampons.
 

Does the tearing of the hymen hurt?
The tearing of the hymen may cause some initial discomfort and slight bleeding. However, there is no reason for women to fear any great pain. On both sides of the vaginal opening, between the edge of the hymen and the minor lips, are the greater vestibular glands (Bartholin's glands), which correspond to the bulbourethral (Cowper's) glands in the male. The greater vestibular glands secrete a small amount of lubricating fluid. However, most of the vaginal lubrication needed for coitus is not provided by these glands but by the wall of the vagina itself.
