一项研究显示,美国人X爱喜欢尝鲜,Z爱的招式愈来愈喜欢非传统的X交方式,例如Z爱时会采用K交、G交等,上了年纪老人大多不戴保险套承受较多风险,但仍充分享受鱼水之欢。

美国印第安纳大学(Indiana University(性健康促进中心(Center for Sexual Health Promotion)针对5865名从14到94岁男女,所做的性经验与保险套使用,分析X交行为和采取的保护措施,这也是美国几十年来规模最大的性行为 调查。

研究人员发现美国人在性生活方面的性别差异与代沟,80岁以上的长者虽然有性生活,但年龄超过50岁的人当中,每5名男性只有1人使用保险套,女性每4人只有1人使用。

相对地,在青少年方面,尽管大多数青少年没有性行为,但当他们进行性行为时,比较有使用保险套概念。研究也发现,有性行为青少年中,男孩说过去10次性行为中,使用保险套比率为79%;女孩为58%。

这项研究也发现,美国男人以插入Y道的方式X交时,最容易达到高潮;美国女人则不管是K交或Y道交,都能容易高潮。而和16年前的研究相比,有 更多美国男女Z爱时K交甚至G交。分析指出,4成20~49岁女性、25~59岁男性都有G交经验;20~49岁不分男女,超过8成都有K交经验。

在高潮方面,问到伴侣最近一次Z爱是否达到高潮,85%的男性认为有,但只有64%女性表示上回Z爱达到高潮。另外,研究也显示有7%女性和 8%男性自称是同性恋或双性恋者。这项研究结果将公布于性医学期刊(Journal of Sexual Medicine)的特刊中。

鏈接:十大同性戀動物
 
波諾波黑猩猩:幾乎所有喜好和平生活的黑猩猩都具有雙重“性”格,它們解決爭端時採用的常常是“做愛而非戰爭”的方式,即便同性之間亦樂此不疲,而且發生過同性戀行為的大約2/3為雌性黑猩猩。



日本獼猴。
日本獼猴:雌性獼猴之間的關係比較緊密,除了發情期,它們的感情比較專一,不會輕易拋棄現有的夥伴,而且它們似乎很滿意它們之間的同性夫妻關係。相比之下,雄性獼猴之間較少發生同性戀行為,經常“一夜情”過後不久就將對方甩掉。

美國野牛:美國野牛中的雄同性戀者更為普遍。因為雌性野牛和雄性野牛一年只有一次交配,雌性野牛發生同性戀的機會就更少了。每當發情期,雄性野牛一天會和同性發生幾次性關係。超過55%的年輕公牛的性生活是在同性之間展開的。

瓶鼻海豚:雄性瓶鼻海豚差不多都具有雙重“性”格,而且它們和同性對象之間的感情相當牢靠,一般容不得第三者插足。

長頸鹿:雄性長頸鹿之間的性活動比較頻繁。雄性長頸鹿發生性關係之前常會摟著對方的脖子親吻長達1個小時。

非洲羚羊:雌性羚羊在發情期和同性夥伴之間的性行為平均每小時會出現幾次,同性戀行為約佔羚羊所有性行為的9%。

黑天鵝:黑天鵝之間的性行為多達20%的發生在同性之間,而且差不多1/4的“同居者”是同性。

海象:雄海象到4歲時性才會發育成熟。此前的性青澀期,它們最有可能和同性之間發生性撫慰。年齡大一點的雄海象具有典型的雙重“性”格,發情期會和雌象交配,剩下的時間則會和同性發生性行為。

灰鯨:它們的同性戀行為更像一次狂歡舞會,5頭灰鯨向四周滾動,同時向周圍不斷噴水,它們的肚子相互頂著,以便互相撫慰。

秘魯岩鳥:大約40%的雄鳥曾有過某種形式的同性戀行為,另有一小部分根本就不曾和異性“同床共枕”過。

僅在澳大利亞,據科學家記錄,許多鳥類的同性戀伴侶都會共同撫養小寶寶,有的雌性通過“一夜情”得到鳥蛋;也有的雌性鳥會把自己的鳥蛋贈送給一 對雄性鳥,由“他們”代為孵化撫養,雄性火烈鳥家庭就屬于後者。令人驚訝的是,這些“雄雄”組合的家庭往往比“雌雄”組合得更為成功。因為“他們”敢作敢 為,富有進攻性,能佔有更多的地盤和資源,所以養育的孩子也就比普通家庭更多。 鳥類還不是同性戀行為最多的動物。澳大利亞生物學家傑夫‧麥克法蘭博士曾對全球現存的動物學文獻進行過一次全面調查。結果顯示,在文獻中靈長類和其他哺乳類動物的同性戀行為最多,接下來才依次是鳥類、爬行類、兩棲類、魚類、昆蟲類和其他無脊椎動物。 科學家認為,動物的同性戀行為有時只是為了取樂,還有的是出于社會紐帶的需要。許多群居動物有著復雜的社會係統,個體需要尋找同盟來獲得幫助和 保護。同性戀關係是找到夥伴的先決條件,單一的異性戀則成了一種劣勢。產于非洲的矮黑猩猩就是這樣的動物,同性矮黑猩猩通過性來化解個體間的衝突。還有一 些動物在成年之前會出現一個階段的同性戀行為,比如雄性小海豚,科學家認為這可以幫助它們彼此之間建立起終身的友誼。

科學家觀察到動物之間存在大量的同性戀行為一場在挪威奧斯陸舉辦的同性戀動物展覽會正引發軒然大波。

這個名為“違背自然?”的展覽力圖向公眾說明:人類同性戀如同鯨魚和蠕蟲的同性戀一樣,並不違反自然法則。

在展覽現場,你可以看到以下圖片:兩隻呈同性戀站姿的雄性長頸鹿,一對雌性同性戀天鵝夫妻,兩條相互挑逗的雄性鯨魚。

展會總監格爾·索裏說:“同性戀行為已在至少1500個動物種類裏被觀測到,其中大約500例已完整記錄在案。”

在幾年前,動物學家還沒有注意到這點。例如,觀察研究非洲長頸鹿的過程中,當一隻雄性長頸鹿騎在另一隻同性的身上,即使是科學們已觀測到動物有射精行為,他們也只單純地把這一現象記錄為“領土之爭”,因為科學家們認為那不是性活動,也不可能是性活動。

另一方面,這也是個禁忌領域。有人指出,動物學家們之所以不敢對此領域進行深入研究是因為這是一個容易引起人們聯想的敏感問題。人們會不自覺地將這些動物,尤其是靈長類動物與人類進行比較。
現在,科學家的觀念已經得到了更新。

美國《內分泌學》雜誌上刊登的一項研究結果稱,至少在130種脊椎動物中也都存在著同性戀行為或者是同性性行為。

澳大利亞生物學家、紐卡斯爾大學的傑夫·麥克法蘭博士對全球現存的動物學文獻進行了一次全面調查。結果顯示,在文獻中,全世界被記錄下有同性戀行為的 動物共450種,其中靈長類和其他哺乳類動物的同性戀行為最多,其次是鳥類、爬行類、兩栖類、魚類、昆蟲類和其他無脊椎動物。在這個調查中,雄性長頸鹿中 之間交往行為的80%都被認定與性有關;超過30%的靈長類動物被認定具有同性戀行為;超過130種鳥類熱衷於同性戀。

關於動物同性戀的原因,目前有多種解釋。有人認為是天生的,有人認為是動物對性識別的錯誤造成的。還有一種觀點認為同性戀只是動物們的遊戲,如加拿大 阿爾伯塔省萊斯布裏奇大學的動物行為教授保羅·瓦齊說:“它們這樣做也許只是為了取樂而已。它們從這樣的行為中得到性快感和性滿足,和進化無關。”

為了探討同性戀調查的可信度 我特地和其他的投票帖做了比較 同性戀的的確是最多人投票 遠超過其他的投票帖 而且帖子已經超過兩年了 所以說可信度是非常的高 不是亂來的哦!!!呵呵!!!

結論是原來馬來西亞 cari 論壇的這個版塊有 55% 的 kaki 有想過要搞同性戀 算是好消息吧?!哈哈

America reveals its sexual secrets

The National Survey of Sexual Health and Behaviour reveals a more adventurous streak to sexual activity than previous studies. Photograph: Edvard March/Corbis

There are 130 pages of it, most densely packed with statistics and the remainder couched in the kind of language that only the most erudite and obsessive of researchers could find remotely arousing. But the most comprehensive national survey of Americans' sex lives for nearly two decades – arguably the most revealing since Dr Alfred Kinsey's two now-celebrated reports some 60-odd years ago – throws up some fairly intriguing findings. And, as always with this kind of behavioural thing, if it's happening in the US, it's more than likely happening here too.

More than we ever used to, for example, we fancy a bit of this and a bit of that (or at least, we're prepared to own up to it). Not that we indulge in all 41 possible combinations of sex acts enumerated by the National Survey of Sexual Health and Behaviour (NSSHB), published yesterday in a special issue of the Journal of Sexual Medicine, every time we have sex. But we do seem to be getting considerably more adventurous: of the five basic acts identified by the study (penile-vaginal intercourse or PVI, solo masturbation, mutual masturbation, oral sex and anal sex), more than 6% of men aged 25-29 claimed to have indulged in each and every one the last time they slept with someone.

Well that, you may object, doesn't prove much. There will always be a small proportion of sexual acrobats (or men who think they are). But how to account for the 16% of women aged 18-24 who reckoned they used four of the five techniques the last time they had sex, or the 8% of women aged 50-59 who said the same thing? "The findings demonstrate the enormous variability that occurs in the sexual repertoire," concludes Debby Herbenick of Indiana University's Centre for Sexual Health Promotion, a leading author of the study of 5,865 US residents aged between 14 and 94. So while "vaginal intercourse was still the most common sexual behaviour" among adult men and women, more of them than ever before reported experiencing what the researchers romantically refer to as "sexual events" that did not feature any actual intercourse at all.

Herbenick puts this down mainly to "evolving and varying definitions of what it means to have 'had sex'". In other words, behaviour that was once considered mere foreplay, a kind of precursor or accessory to the main event – the starter, if you like – is increasingly becoming the main course. (And it is worth pointing out that the statistics above refer only to the respondents' last sexual experience, not necessarily to what they get up to when they are really setting out to have a good time).

Half a century ago, the writer Somerset Maugham opined that there is "hardly anyone whose sexual life, if it were broadcast, would not fill the world at large with surprise and horror". He may, finally, be right. The study doesn't delve much into the reasons why our sexual behaviour is evolving in this way. (Indeed, it may have ended up with some even more evolved behaviours – and probably a far larger number of sex act combinations – had it chosen to ask its respondents about their use of sex toys and pornography, which it didn't.) But nonetheless, the NSSHB pretty much puts paid to any lingering notions that repressed Anglo-Saxons are less adventurous in bed than, say, the Italians or French. The missionary position may not quite have died a death, but it's certainly no longer the beginning and end of what we now consider as sex.

Oral sex, for example, has become positively banal. Some 88% of men aged 30-39 have performed oral sex on a woman, 69% of them in the last year. Likewise, nearly 20% of boys aged 16-17. More than half of all women surveyed said they had received oral sex from a male partner in the previous year, while 12% of women aged 14-15, 23% aged 16-17 and well over half of those aged 18-49 said they had given a male partner oral sex.

Masturbation, likewise, is universal. Between 28% and 69% of men in each age group reported having masturbated alone during the past month; and solo masturbation emerged as the most common sex act among 14-24 year-old men and the over-50s. Among women, more than half aged 18-49 said they had masturbated alone in the previous 90 days, pretty much regardless of whether or not they were in a relationship. Nearly a quarter of all women said they had engaged in mutual masturbation with a male partner in the previous month.

Same-sex activity appears to be on the rise, or at least less taboo

More surprisingly, perhaps, the reported rate of anal sex has also increased dramatically, effectively doubling since the National Health and Social Life Survey was carried out by researchers from the University of Chicago in 1988. That study suggested around 12% of American women in the 25-29 age group had experienced anal sex in the last year; that figure has now risen to 21% (and also applies to the 30-39 age group). Some 20% of American 18- to 19-year-old girls have had anal sex at least once in their lifetimes, the new study shows, rising to more than 45% among 25-29 year olds.

Same-sex activity also appears to be on the rise, or at least less taboo (rather than through face-to-face interviews, the new survey was carried out online, a method believed to encourage more open and honest responses). While only about 7% of men and women identified themselves as "other than heterosexual", far more said they had engaged in some form of sexual activity with a member of the same sex. Nearly 15% of women in their 30s, for example, reported having performed oral sex on another woman at least once in their lifetime, while 13% of men over 40 said they had done the same to another man and 50% of men aged 50-59 said they had received it.

While we may be doing more stuff, though, we are not necessarily talking about it. According to Jocelyn Elders, the former US surgeon general, American society continues to view sex "primarily in negative terms"; she has used the report's evidence to argue for a more "open, frank conversation" in American society. "We have a sexually dysfunctional society because of our limited views of sexuality and our lack of knowledge and understanding concerning the complexities and joys of humanity," Elders writes in an introductory paper to the report. "We must revolutionise our conversation . . . to a discussion of pleasure."

Perhaps the most notable consequence of this expanded smorgasbord of sex does, though, appear to be that the whole business has become more pleasurable for women. While men were, on balance, more likely to reach orgasm during vaginal sex, women reported they were far more likely to if their partners adopted more than just one of the five basic techniques – and nearly 90% said they did so when they or their partner used all five. (More disturbingly, a startling number of women – almost a third – reported experiencing some form of genital pain during their most recent sexual encounter, against just 5% of men.)

Not that this more varied sexual diet and greater degree of female sexual satisfaction has done much to reduce the problem of what researchers call "the orgasm gap": in other words, the number of women who actually experience orgasm during sex, as opposed to the number of men who think they do. The NSSHB reports that 64% of women indicated they had reached orgasm in the course of their most recent "sexual event", whereas a fairly staggering 85% of men reported that their partner had done so during their most recent encounter. Some, of course, may have been having sex with other men, but that can hardly account for a 21% difference in perception.

Few young American teenagers seem to be having sex with anybody apart from themselves

There was more reassuring news, though, for those who fear that amid growing concern about teenage sexual development – much of it linked to mobile phone "sexting", social networking websites such as Facebook, and computer-based instant messaging services – very few young American teenagers seem to be having physical sex with anybody apart from themselves. Of the 14- to 16-year-old boys and girls surveyed, only around 10% said they were engaging in any kind of sexual activity with a partner – whereas 62% of boys, and 40% of girls, in the same age group were happy to admit to masturbating on their own during the last year.

The highest rate of condom use (the study was funded by the manufacturer of Trojan condoms) was also found to be among 14- to 17-year-olds. Nearly 80% of the boys and 69% of the girls surveyed said they used a condom the last time they had sex, against 25% for all the men in the study, leading the researchers to conclude that condom use had now become "the norm" among teens. Rates of condom use among black and Hispanic males were also considerably higher than among white men, perhaps showing that HIV-Aids awareness campaigns in these communities, where the disease is proportionately more prevalent, were making progress. "Our findings also show that condoms are used twice as often with casual sexual partners as with relationship partners, a trend that is consistent for both men and women across age groups that span 50 years," Herbenick said.

Cheering findings, too, for the over-60s: both men and women continue to be both active and adventurous in bed between the ages of 60 and 69, with 38% of men and 25% of women indicating they had been given oral sex by a partner of the opposite sex at some stage during the previous 12 months. Past 70, 19% or men and 8% of women reported they were still enjoying regular oral sex as part of their overall sexual activity. Somerset Maugham, one imagines, would be thrilled.

同性戀是不自然的嗎?!

先來看看動物界的同性戀現象。

在我所參考的文獻中 動物同性戀的比例可以從 8% 到 100%。當然這其中也包栝了雙性戀。

在這裡,非常明顯的,如果說多數才是自然,那實在是無法說佔多數的動物同性戀或是雙性戀是不自然的。

當然你可以說人類怎麼可以和動物來相比較?!OK 。。。也許你的確很優越,是萬物之靈。

但是不要忘記了, 人類 其實也不過只是 動物 的其中一種。

就算是以宗教的理由,只有人類才會有靈性,所以不可以將人類和動物來相比較。但是請某些自大狂妄的宗教徒注意,千萬不要忘記,這個世界上不是全部的人都有宗教信仰,而且宗教也不是只有一個,無神論者是不會相信什麼上帝創造人類那一套的!

要說服別人,就請老老實實搬出數據,講道理。不要抬出一大堆無法證明它存在又無法證明它不存在的東西來狡辯,用沒有事實根據的東西來說明自己的立場,是沒有任何意義的!!!

而且在動物的同性戀行為研究不發達之前,很多人攻擊同性戀是不自然的理由是 “因為其他的動物都沒有搞同性戀,所以同性戀是不自然的”。哦!!!

呵呵!!!

~~~~~~~~~~~~~~~~~~~

動物界的同性戀行為是指已被記錄的人類以外的動物的同性戀、雙性戀和變性行為的跡象。這些跡象包括性交、愛撫、愛慕行為、擇偶(英語:pair bond)傾向及幼兒監護(英語:parenting)行為。加拿大生物學家布魯斯·貝哲米(英語:Bruce Bagemihl)在1999年發表了一分有關檢閱接近1,500個動物物種同性戀行為的文獻,涉及物種從靈長目到棘頭動物門,對其中500個物種又有更詳細的著墨。

動物性行為(英語:Animal sexual behavior)在同物種之間也有許多不同的形式,而這些行為背後的動機和意思至今還沒被人類完全了解,因為大部分物種本身也未被研究透徹。[3]貝哲米說道:「動物王國中同性、雙性及非交配性行為的普及性與多樣性都遠超大部分科學學派和社會人士所願意接受的程度。」[4]挪威動物學家Petter Bøckman(書面挪威語:Petter Bøckman)[5]就批評過往動物學家在遇上動物同性性行為時都會出於懼怕觸犯人類社會的禁忌而無視或歪曲其觀察結果。[6]

對於反對同性戀權利(LGBT運動)的宗教及社會團體而言同性戀在自然界的存在也是個富有爭議性的題材,因為這些觀測和研究成果會引起同性戀在人類社會自然而發的合理性爭論[7],亦反駁了中世紀基督教將同性戀列為「違反自然界的罪(拉丁文:peccatum contra naturam / peccatum Sodomiticum / 所多瑪罪,即雞姦罪)」。[8]有些評論就反駁以動物的行為來解釋人類道德觀念是不適當的。[7][9][10]

貝哲米說:「除了蚜蟲屬(英語:Aphis)和海膽綱這些完全沒有性行為的品種外,沒有任何一個物種有證據顯示同性戀行為是不存在的,而且雌雄同體的物種都有雙性戀傾向,對牠們來說同性戀並不是問題。」

另外具有持久同性配偶關係的動物也不局限於一夫一妻制的物種,以綿羊為例,有8%的公羊在雌雄皆充裕的環境下還是選擇雄性作伴,這些結合多年的公羊的視前區(英語:Preoptic area)前部下丘腦(控制體溫、飢餓、性慾等)的細胞組織比母羊要大得多。[15]

德國不萊梅哈芬的動物園飼養的南美瀕危品種企鵝發現了5對中有3對是男同性戀組合,他們也像羅伊與塞咯曾經以石頭當作蛋來孵育。動物園為了獲得新生幼兒而從瑞典引入4隻雌性企鵝並拆散同性組合[18],結果計劃失敗並且引來德國的同性戀權益組織抗議。[19]

蜻蛉目的昆蟲在交配時雄性會以其泄殖腔在雌性頭部留下獨特的傷痕,11個品種包括豆娘和蜻蜓有20至80%的雄性的頭部都發現有這種傷痕,推論出有頗高的蜻蛉目同性性行為。[20][21]

The correct usage of the term homosexual is that an animal exhibits homosexual behavior or even same-sex sexual behavior; however, this article conforms to the usage by modern research[13][14][15][16][17] applying the term homosexuality to all sexual behavior (copulation,genital stimulation, mating games and sexualdisplay behavior) between animals of the same sex. In most instances, it is presumed that the homosexual behavior is but part of the animal's overall sexual behavioral repertoire, making the animal "bisexual" rather than "homosexual" as the terms are commonly understood in humans,[16] but cases of homosexual preference and exclusive homosexual pairs are known.[18]

While studies have demonstrated homosexual behavior in a number of species,Petter Bøckman, the scientific advisor of the exhibitionAgainst Nature? in 2007, speculated that the true extent of the phenomenon may be much larger than was then recognized:

    No species has been found in which homosexual behaviour                 has                 not                 been shown to exist, with the                 exception of species that never have sex at all, such as                sea                 urchins and aphis.             Moreover, a part of the animal kingdom is                hermaphroditic, truly bisexual. For them, homosexuality is not an             issue.                        —[20]

An example of overlooking homosexual behavior is noted byBruce Bagemihl describing mating giraffes where nine out of ten pairings occur between males.

    Every male that sniffed a female was reported as sex,                 while anal intercourse with orgasm between males was only "revolving                 around" dominance,              competition or                greetings.—[22]

    In one study,                 up to 94% of observed mounting                 incidents took place between two males. The proportion of  same sex activities varied between 30 and 75%, and at any given time one                 in twenty males were engaged in non-combative necking behavior with                 another male. Only 1% of same-sex mounting incidents occurred between          females.[63]  
               
    在長頸鹿的交配行為之中發現,最高可以觀察到有 90%  的比率是在雄性和雄性的長頸鹿之間發生的。

An estimated one-quarter of all black swans pairings are homosexual and they steal nests, or form temporary threesomes with females to obtain eggs, driving away the female after she lays the eggs.

黑天鵝之中有 25% 是搞同性戀的。

The Bonobo, which has a matriarchal society, unusual amongstapes,is a fullybisexual species—both males and females engage in heterosexual and homosexual behavior, being noted for female-female homosexuality in particular.

倭黑猩猩是 100% 的雙性戀,不管是雄性還是雌性。
