Amazing big data: what is the "normal" sex life? -Sex, big data-IT information
Beijing time on March 29, according to foreign media reports, human sexuality is very complex. People′s preference for sex may and the food tastes the same type. And like food tastes and preferences of each country is different, everyone′s tastes are different, even the preference of each day will be different.
For this reason, it is difficult to say what is a "normal" sex life. Scope of our choice in this matter is too big, alone at last count is impossible to summarize the feelings of the majority. Therefore, the BBC to study the statistics from our sexual desire, different methods of our sheets, trying to sum up a complete set of "sex" spectrum.
Needless to say, this project will certainly encounter some serious problems. In some places, talking about sex that love is still a taboo, respondents may not freely; or, conversely, respondents can use flowery language to answer for myself hyperchromic, this would result in investigations of sexual confidence is very low. Therefore, we should not see these statistics as evidence of the fact, but should be generally view them, use them to learn about 21st century human sexuality have different choices.
How much we desire to have sex? Not every sexual desire. 0.4% to 3% of people have no desire for sex.
It is difficult to use data to measure people′s sexual orientation. Homosexual persons may number from 1% to 15%, depending on whom you are asking who is using the inquiry methods, and what you ask is the attraction, personal behavior or identity. Despite such problems, but recent surveys from around the world have shown, some people that there is no desire (but this does not mean that they have never established relationships with others). Just like any other sexual orientations, such persons as a proportion of the not yet clear (most researchers believe is 1%). But in this part of sex without the crowd, there are an increasing number of people are proud of this, and a series of promotion campaigns.
We will have sex with who? 53% chose partners for a long time, 24% people will choose a partner, 12% chose friends, 9% chose strangers, there are 2% people choose to prostitutes.
People often have a misconception that only sex with a stranger, is the casual sex. But, in fact, that casual sex is also divided into many forms. 2009 in the United States carried out a survey of someone new, "one night stand" is actually a relatively rare (although teens and at the age of more than 20 data slightly higher, but from age 20 to 60 years old, each age difference between not-so-obvious). In other words, nearly half of Americans, the sex is "a complicated thing".
We long for intercourse? 18% who never once last year, 8% people once a year, 28% of the 1 to 2 times a month, 40% of the 1 to 3 times a week, people 6.5% more than 4 times a week.
These data come from the United States of "global love investigation", surveyed more than more than 50,000 adults over the age of 18. Though frequency increases with age and their sex lives decreased, but does not drop as low as you might think. A recent for the elderly (mean age 70 years) survey showed that at least half of the respondents have sex two or more times every month, 11% people have sex a week and enjoy.
What are the way we have sexual intercourse? In the population aged 18 to 59 years of age, during the last sexual intercourse, 86% women and 80% men had vaginal intercourse, 67% women and 80% men through oral sex, there are 3.5% women and 9% men anal sex.
Data from one of the above items in the United States conducting anonymous surveys, respondents almost 2000 people, ranging in age from 18 to 59 years old, they were asked what they were using at last sex lovemaking.
Each fair lasts how long? Lesbian 30-45 minutes at a time, straight and gay 15-30 minutes at a time.
Though women reported having sex more often than gay and heterosexual lower, but as far as Canada and the United States, a survey showed, their number, though small time is longer than the average person.
How many of our people who pretend to have orgasm? 50% women and 25% men pretending to have an orgasm.
People often think that only women will fake orgasms. But United States according to a recent survey, there are more men at a fake orgasms when sex. Reason may be the same as you think: they may not have had sex, but does not want to let their partners too. However, even though they would do, but only 20% of men think their partner will fake orgasms.
大数据惊人：什么才是“正常”的性生活？ - 性生活,大数据 - IT资讯
北京时间3月29日消息，据国外媒体报道，人类的性生活是非常复杂的。人们对性爱的偏好种类可能和食物的口味一样多。并且就像食物的口味一样，每个国家的偏好都有所不同，每个人的偏好也有所不同，甚至每个人每天的偏好也会不一样。
由于这个原因，我们很难说什么才是“正常”的性生活。我们在这件事上选择的范围太大，单凭一次统计是不可能概括出大多数人的感受的。因此，BBC对统计数据进行了研究，从我们对性的渴望程度，到我们滚床单的不同方法，试图归纳出一套完整的“性生活”光谱。
不用说，这个计划肯定会遭到一些严重的问题。在有些地方，谈性说爱仍是一种禁忌，调查对象可能不会畅所欲言；或者反过来，调查对象可能会用华丽的辞藻来为自己的回答增色，这些都会导致对性行为的调查可信度很低。因此，我们不应把这些统计数据当成确凿的事实，而应该笼统地看待它们，利用它们来了解21世纪的人类性生活有哪些不同的选择。
我们有多渴望性爱？并不是每个人都会产生性欲望的。有0.4%到3%的人对性爱毫无欲望。
我们很难用数据来衡量人们的性取向。同性恋人士的数量从1%到15%都有可能，这取决于你询问的对象是谁，采用了怎样的询问方法，以及你询问的是吸引力、个人行为还是身份认同感。尽管存在这样的问题，但近期一些来自世界各地的调查纷纷显示，有些人对性是完全没有欲望的（但这并不意味着他们从未与他人建立过恋爱关系）。就像其它性取向一样，这类人所占的比例目前尚不清楚（大多数研究人员认为是1%）。但在这部分对性爱无感的人群中，有越来越多的人开始以此为豪，并开展了一系列推广运动。
我们都会和谁进行性交？53%的人选择长期伴侣，24%的人会随意选择伴侣，12%的人选择炮友，9%的人选择陌生人，还有2%的人选择妓女。
人们往往有一种误解，认为只有和陌生人性交，才算是随随便便的性爱。但事实上，这种轻松随意的性爱也分为很多种形式。2009年在美国开展的一项调查显示，与陌生人发生的“一夜情”其实是相对罕见的（虽然十几岁和二十几岁时的数据稍微偏高一些，但从二十岁到六十岁，每个年龄段之间的差异就不那么明显了）。换句话说，对于将近一半的美国人来说，性爱都是“一件复杂的事情”。
我们多久进行一次性交？18%的人去年一次都没有，8%的人一年一次，28%的人一个月1到2次，40%的人一周1到3次，6.5%的人一周超过4次。
上述数据来源于美国的“全球性爱调查”，调查对象包括5万多名18岁以上的成年人。虽然性生活的频率会随着年龄的增长而下降，但并不会降得和你想象的一样低。近期一项针对老年人（平均年龄为70岁）的调查显示，至少一半的调查对象每个月有两次以上的性生活，11%的人每周都有性爱可享受。
我们进行性交的方式都有哪些？在年龄18岁至59岁的人群中，在上次进行性交时，86%的女性和80%的男性采用了阴道性交，67%的女性和80%的男性进行了口交，还有3.5%的女性和9%的男性进行了肛交。
上图中的数据来源于一项在美国开展的匿名调查，调查对象将近两千人，年龄从18岁到59岁不等，他们被询问了他们在上次性爱时采用了哪些做爱方式。
每次性交会持续多久？女同性恋每次30到45分钟，异性恋和男同性恋每次15到30分钟。
虽然女同性恋上报的做爱频率比男同性恋和异性恋要低，但据加拿大和美国的一项调查显示，她们的次数虽少，时间却比一般人要长。
我们有多少人假装过高潮？50%的女性和25%的男性都假装过高潮。
人们通常认为，只有女性才会假装高潮。但美国近期开展的一项调查显示，有相对较多的男性也会在某次性爱时假装高潮。原因可能和你想象的一样：他们当时可能没有做爱的心情，但又不想让自己的伴侣扫兴。不过，虽然他们自己也会这么做，但只有20%的男性认为自己的伴侣会假装高潮。
