Hello everyone and welcome to DNews, I’m Dr. Crystal Dilworth here to discuss Intravaginal Ejactulatory Latency Time;

嗨大家好，歡迎收看DNews，我是Crystal Dilworth 博士，在這裡跟你討論「陰道內延遲射精時間」，

otherwise known as the time it takes a heterosexual couples to have sex.

也就是一般異性戀伴侶做愛所花的時間。

So how long “should” you be having sex for ? And are you…“normal”?

所以你到底應該要愛愛多久呢？你「正常」嗎？

Well in attempting to answer these questions, I discovered that “normal” has actually changed with societal expectations

在試著回答這些問題時，我發現了正常的定義其實是隨著社會期待在改變的，

and the average length of intercourse has varied over time.

平均的性交時間也隨著時代改變。

So it’s not just biology that we are dealing with here,

影響我們的可不只有生理上的因素，

how long we ''think'' we should be having sex is an influence too.

還包含我們認為我們自己應該要做愛多久。

In the late 1940s at the time of the famous Kinsey Report,

在1940年代晚期，著名的的Kinsey報告指出，

75% of males surveyed reported intercourse lasting approximately 2 minutes.

75%受調查的男性反映他們性交的時間約在兩分鐘左右。

A number that seems objectionably short to me personally

這數字對我來講真是令人厭惡的少啊，

and could warrant a premature ejaculation diagnosis in these modern times.

且在現今社會，這可以被開立早洩的診斷。

For the record, the diagnosis of PE is heavily weighted towards self and partner reported satisfaction,

不過我有言在先，早洩的診斷是由自己跟伴侶的滿意度來決定的，

but one to two minutes is commonly considered to be premature.

不過通常來說，一、兩分鐘是太短了。

Researchers are finding that since the late 60’s, the start of the feminist movement and sexual revolution,

研究人員發現在1960年代晚期，女性主義、性革命的啟蒙之後，

intercourse has been taking us slightly longer. How long?

性行為的時間就有稍微的拉長了。多長呢？

Well, survey data from studies done at the University of New Brunswick show that

在New Brunswick大學做的研究指出，

duration of vaginal intercourse is now reported to fall within a range of 5 to 10 minutes,

「陰道內交合」的時間來到了5到10分鐘的區間內，

with durations in excess of 20 minutes being undesirable to most study participants.

對大部份的受測者來說，持續超過20分鐘是不合需求的。

So that average sweet spot is really, as one scientist put it:

誠如一位科學家所言，平均來說，

“approximately the duration of one Marvin Gaye song.”

最好的時間長短大概跟一首Marvin Gaye的歌差不多。（美國靈魂樂歌手）

Sadly, sex research is notoriously penis-centric and historically hetero-centric,

不過令人遺憾的，這類的性調查是備受爭議地，因為只以男性為中心，且因歷史的緣故，也以異性戀為中心，

so these averages only apply to the time it takes for male ejaculation with a female partner

所以這些平均時間只適用於男性對女性伴侶的射精行為

and only the more recent studies investigate qualitative measures like sexual satisfaction.

直到近期的研究才有採用品質化的測量指標，像是性滿意度。

In a 2004 study, participants were asked to report how long they wanted sex to last as well as the actual duration of their intercourse.

在一個2004年的研究中，受測者們被問及他們理想的性行為及實際性交的時間長度。

Female study participants indicated that they desired an average of 7 minutes longer then what was standard with their current partners,

平均而言，受測女性們想要的性交時間比他們現在伴侶的標準表現，還要多7分鐘 ，

and men reported wanting another 11 minutes.

男士們則想要多個11分鐘。

The funny thing about this survey, is that when asked about duration of foreplay,

不過這調查有趣的是，當男女雙方被問及到前戲的長度時，

both men and women also reported desiring an average of 5 or 10 minutes longer respectively.

他們都不約而同的想要更久些，男生想要再5分鐘，女生則是10分鐘，

So, take a look at your partner. Are they smiling?

所以看一下你的伴侶吧。他們在微笑嗎？

If not, it might be time for a conversation about sexual expectations and needs.

如果沒有的話，或許是時候溝通一下你們的性期待及性需求了。

Because, ultimately, it doesn’t matter what study group survey subjects think, or what your friends, neighbors,

因為最終，無論那些受測者、你的朋友、鄰居

or professionals on your computer screens are doing.

或者是「電腦上的那些專家們」怎麼做。

What matters is self and partner satisfaction.

重要的是你跟你伴侶的滿意程度。

That's something to keep in mind as you check out this video where Julia asks the question “How much sex should you be having?”

這是當你觀賞Julia在這集裡提問「我們應該要有多少性行為？」時，你得記住的一點。

So, are you sexually normal?

所以你在性方面正常嗎？
