These 5 Sex Positions Will Help You Last Longer In Bed, According To A Sex Doctor



Let’s face it: Every guy wants to be a satisfying sex partner, but not every guy can “run the entire marathon” when it’s show time. When you finish too early, it can make your partner feel unhappy and make you feel inadequate. That’s a bad situation all around!

Luckily, there’s a solution for sprint runners looking to become endurance champs. We asked our friends at the Between Us Clinic—which provides an online treatment program for men experiencing premature ejaculation—about whether there was something men could do to last longer in bed. Their answer? Try some new positions!

How positions can make a difference

There are sexual positions that can help to delay ejaculation until you and your partner are both ready. Some of these helpful positions rely on reducing stimulation to the ultra-sensitive underside of the penis, while other positions are focused on reducing speed and force of thrust, enabling a slower and more satisfying sexual experience for both partners. Most men are more aroused in a position in which the man is on top of the woman in a more dominant role. However, when you are in a more passive role, you can pay greater attention to the sensations from the stimulation which is an important part of controlling ejaculation.

Muscle tension in the legs and pelvic region can also lead to greater chances of orgasm, and exerting control over these factors can help you to delay ejaculation and ensure that you and your partner enjoy the experience to its fullest.


First position: “Side-by-side”

How to do it

One partner lies on their left side, one on their right, so that both partners are face-to-face. The woman parts her legs, draping one over the backside of the man so that he can penetrate her. This allows both partners to have some control over the movement and stimulation.

How it helps

Although both partners have an equally active, yet equally passive role when using this position, the position places a natural limit on the amount of forceful and deeply penetrative thrusting that is possible. This allows the man to focus more of his attention on the sensations he is experiencing in a slightly passive role, and it also helps to control the level of muscle tension in the man’s legs and pelvic area.


Second position: “Cowgirl”

How to do it

In this position, the man lies flat on his back on the bed, floor, or couch while the woman straddles him as if she is riding a horse like a “cowgirl.” She controls the penetration almost entirely in this position, while the man remains relatively passive.

How it helps

Because the woman is on top and controlling the action, the urge to use forceful, fast thrusts to penetrate more deeply can be kept in check. By leaving the control over the penetration up to her, there is a better chance of lasting longer and allowing her to find satisfaction by moving the way she likes.


Third position: “Missionary”—with a twist

How to do it

While the woman lies on her back with her legs apart, the man faces her while on his knees and, without penetrating her, rubs his penis against the woman’s vulva and clitoris (that’s the twist).

How it helps

By deliberately shifting stimulation to the top side of the penis and avoiding actual penetration, the man can avoid overstimulation of the most sensitive area of his penis. Also, the stimulation to the woman’s outer genitals can enhance her sexual experience, so everyone can enjoy the sensations that much more, and for that much longer.


Fourth position: “Spooning”

How to do it

The man lies down on the bed or floor on his side, then snuggles up against his partner’s backside until their bodies are nestled together like spoons. The woman can then lift her leg slightly to allow the man to penetrate her from behind.

How it helps

This position keeps the depth of sexual penetration under control, and also reduces the amount of movement that is possible during intercourse. Because it is nearly impossible to thrust deeply and forcefully while spooning, it’s possible to have a longer-lasting, more satisfying sexual experience in this position.


Fourth position: “Both seated”

How to do it

In this position, the man sits on the bed or floor while the woman sits in his lap, facing him, with her legs curled around his back for support and balance. This is another position in which the woman plays the larger role in controlling the action.

How it helps

This position is helpful with delaying climax, in part, because it’s somewhat awkward. It’s not easy to thrust fast or hard while seated, and this allows the man to last longer before ejaculating. This position lends itself well to slow, partner-focused sex rather than feisty, fast sex.


A final word on delaying climax

By being in touch with your body and knowing where the most nerve endings are (and thus, which areas are most sensitive), you can get creative with sexual positions and last longer in bed. Try using fewer positions that stimulate the tender underside of the penis or that result in opportunities for ultra-deep, forceful penetration. Instead, try positions that call for slower movements and more sensation focused on the top side of the penis, as well as those that allow for more relaxation of the pelvic muscles and the muscles in the legs. These more passive, less dominant positions allow for you to focus on the feelings and draw out your sexual experience. You’ll last longer, and your partner will probably experience more satisfaction than ever before.


Bat Bot is an autonomous drone that mimics a bat’s flight


For roboticists working in the field of biomimetics, copying a bat’s complex flight patterns has been a difficult problem to solve. Or, as Caltech professor and Jet Propulsion Laboratory researcher Soon-Jo Chung put it during a press conference, "bat flight is the holy grail of aerial robotics." And according to a new research paper published by Chung and his JPL colleagues in the journal Science Robotics this week, that holy grail has officially been discovered.

Robotic birds and winged insects are relatively easy to create, but with over 40 joints in their wings, bats offer a new level of intricacy. By simplifying that wing structure into just nine key joints covered by a flexible membrane, however, the team successfully created the first Bat Bot. Built from carbon fiber bones and 3D-printed socket joints, Bat Bot weighs just 93 grams and the silicon-based wing membrane is only 56 microns thick with a roughly one-foot wingspan. "Our work demonstrates one of the most advanced designs to date of a self-contained flapping-winged aerial robot with bat morphology that is able to perform autonomous flight," Alireza Ramezani, one of the paper’s co-authors said.

Like a real bat, Bat Bot can move each wing independently and constantly change each wing’s shape to perform complex maneuvers that would be impossible otherwise. The flapping motion also conserves battery power, making it both quieter and more efficient than its fixed-wing or quadcopter counterparts.

Although the battery technology is still too clunky to allow for long flights, the research team believes Bat Bot’s agility would make it ideal for search and rescue operations or other applications in tight, urban environments. For now, however, the team is working on their next major milestone: teaching Bat Bot how to perch like its SCAMP cousin.

Twitter staff are donating almost $1.6 million to fight Trump’s immigration ban (TWTR)


Twitter staff are donating almost $1.6 million (£1.2 million) to the American Civil Liberties Union (ACLU) to fight President Donald Trump’s ban on travellers from seven majority-Muslim countries.

The donation was earlier reported on by TechCrunch and BuzzFeed, and a Twitter spokesperson confirmed the news to Business Insider.

Twitter employees raised $530,000 (£421,000) for the rights organisation — and this amount was matched by executive chairman Omid Kordestani and CEO Jack Dorsey, bringing it to $1.59 million.

In a company-wide email obtained by TechCrunch, General Counsel Vijaya Gadde wrote: “Our work is far from done. In the coming months we’ll see a flurry of legal challenges, legislative pushes and public pronouncements. But as long as civil liberties are threatened, I’m proud to know that as individuals we will stand up to defend freedom and look after people.”

President Trump’s executive order on immigration has provoked fury among the tech community, with companies including Facebook, Google, and Airbnb condemning the suspension of the United States’ refugee program and bar on visitors from Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen.

Google has launched a crisis fund of up to $4 million (£3.1 million) that it may donate to the ACLU and other organisations battling the executive order and providing relief for those affected. Over the weekend that Trump signed the order, the ACLU received $24 million (£19 million) in online donations — a radical increase on the $4 million that the non-profit normally gets in an entire year.

Twitter CEO Jack Dorsey has also spoken out against the executive order on the social network, tweeting on Saturday: “The Executive Order’s humanitarian and economic impact is real and upsetting. We benefit from what refugees and immigrants bring to the U.S.”

See the remarkable difference between a crash test 20 years ago vs one today


Crash testers Euro NCAP have released video footage highlighting the improvements to car safety over the past 20 years.

The footage shows two different crash tests, one from 1997 and one from 2017. In each of the tests the two cars, a Rover 100 and a Honda Jazz, are travelling at the same speeds, but the results are dramatically different.

Euro NCAP say that over the past 20 years the tests have helped to halve the number of people killed on the UK’s roads.

Uber wants to use Facebook data to show what you have in common with other UberPool passengers


Uber has filed a patent that might make its UberPool carsharing
service slightly less creepy, by showing passengers friends or
interests they have in common.

UberPool patent filing
How Uber wants the friend feature to


Judging by the filing, Uber will ask you to connect your Facebook
profile with its app when you request an UberPool. It will
do the same for anyone you’re about to share a ride with and if
you have friends in common, Uber will let you know.

UberPool patent filing explanation
How Uber wants the feature to work.

Uber doesn’t just want to look for mutual Facebook friends or
friends of friends. It might also look for:

  • Whether you went to the same college
  • Whether you ever worked at the same company
  • Whether you grew up in the same place
  • Whether you were born in the same country as each other
  • Whether you have the same hobbies

According to the filing, the idea is to make sharing an UberPool
with complete strangers less awkward. But it’s possible knowing
this much information about a stranger might make the service
seem more, rather than less, creepy.

Uber’s also proposing a kind of exclusive UberPool where riders
can proactively request to share a car only with people who have
common links.

The company also seems to want the increased social integration
to run both ways.

The filing outlines an “Uber there” feature that could be
embedded into an event invitation. For example, you could be
looking at a Facebook invite to a friend’s birthday at a bar, hit
the embedded “Uber there” button, and share a ride there with
friends of friends who may live nearby, all without leaving

It’s worth noting Uber has filed but not been granted the patent,
meaning the data mining feature may never see the light of day.

If it does, all of this might make UberPool more palatable
to anyone worried about sharing a car with strangers. At the end
of last year, Uber had to issue rules for carsharing
, warning them not to flirt with or vomit on fellow

Here’s the patent in full.

459 Million Bitcoins: Exchange Volume Reached Peak Levels in Q4


bull, bear

The fourth quarter of 2016 was a volatile period for the price of bitcoin, as speculation climbed to new heights and exchange-traded volume reached peak levels, according to data provider Bitcoinity.

Even before bitcoin approached $1,000 at the end of Q4, a record 114m bitcoins were exchanged in the month of October alone.

The record was shattered in the following month with 175m bitcoins traded in November, followed by a slight downtick in December with 170m bitcoins exchanging hands.

Exchange-traded volume for bitcoin experienced a 275% quarter-over-quarter increase to 459 million bitcoins in Q4 of 2016, from 122 million bitcoins in Q3.


Compared the figures year-on-year, trading volume in Q4 of 2016 jumped up 206% from 150m bitcoins traded in Q4 of 2015.

Q4'15 and Q4'16 BTC Exchange Traded Volume

China’s dominance

Yet, the volumes from Q4 only tell part of the story.

A large concentration of exchange-traded volume typically occurs in China’s ‘Big Three’ bitcoin exchanges: BTCC, Huobi and OKCoin (at least, before they recently announced sweeping policy changes).

The trading volume of these three alone totaled 452m bitcoins in Q4 of 2016, a staggering 98% of all trading volume for the quarter, but there is reason to believe that figure may be inflated.

Some investors and entrepreneurs remain skeptical of this notorious metric, stating that the “true volume“, or what the volume would have been if these exchanges charged trading fees, is closer to 85%.

This discrepancy may not sound large, but at 98% of exchange traded volume, China’s volume is about 49x the rest of the world, whereas at 85%, Chinese exchange traded volume is only around 6x as large. That’s an order of magnitude reduction in sheer volume size (approximately 8.6x).

Clearer picture

As the zero-fee era of Chinese exchanges comes to a close and markets begin to stabilize following the election of Donald Trump, it’s anyone’s guess as to where exchange traded volume will fall at the end of the first quarter of 2017.

However, given the shake-ups at the ‘Big Three’, it appears the cryptocurrency community will get a look at the ‘true volume’ results for exchange traded bitcoins in the coming months.
