Last Longer In Bed – Facts And Tips

The desire to extend playtime beyond its usual duration is a common one among both men and women. If both partners are interested in this, it makes sense to learn some tips about how to last longer in bed – provided that both partners’ expectations are realistic. If one or both partners place unrealistic expectations on the man’s stamina, then performance anxiety can set in and further disrupt pleasure. Since sensual activity is an important part of psychological, relationship and manhood health, couples should know not only tips for lasting longer, but facts that dispel common misconceptions about a man’s lasting powers as well.

1. Get the facts straight. There is a notable discrepancy between what people want in bed and what they can reasonably expect (without proper preparations). Consider the following bits of data:

• A Cosmopolitan magazine survey of more than 2,500 women found that more than 70% said their desired length of lovemaking (from penetration to male finish) is over 10 minutes, with most saying 15-25 minutes.
• The same magazine surveyed about 30,000 men and found that, on average, they want longer sack sessions (including pre-play) to last 35-40 minutes.
• The average man can handle 3-7 minutes of continual thrusting before releasing.

Clearly, some of people’s expectations around sensual activity are unrealistic – at least unless they take special measures to lengthen the duration of the activity. It’s not that men have a problem – only 2-5% of men qualify as suffering from early on release, which is defined as finishing within one minute. Lasting for a short period of time is completely normal, so couples need to understand that, first, it’s not a man’s fault, and, second, both can take steps to lengthen their encounters.

2. Proper training is key. There are a couple things men can do outside of partner play to increase their control over release timing. One is to perform kegels; this is done by contracting the muscles that control the flow of urine through the male organ. The exercise is also known to strengthen tumescence function. 3 sets of 15 reps spread throughout the day is sufficient to make a difference, and they can be done anywhere.

Second, men can use their self-stimulation routine to up their bedroom stamina. This is done by employing a method called edging in which a man brings himself to the brink of release, then stops and waits until he begins to soften to start up again, repeating the process 3 or 4 times before allowing release. This trains him to better control the time of release.

3. Vary the speed. Remember: 3-7 minutes of continual thrusting is the normal time it takes for a healthy man to finish. If both partners are fond of the jackhammer style of sensual activity, fast and constant, it’s not reasonable to expect much longer from a man. Therefore, when he feels close to finishing, he can take this as his cue to slow down – kind of like edging, but with a partner.

4. Try the “7 and 9” method. The 7 and 9 method dictates a more structured approach to varying speed. The man thrusts fast 7 times, then 9 times more slowly and repeats.

5. Have mid-play. A man can maintain both male and female organ stimulation without thrusting in and out. When he’s getting close, he can pull out and rub the head of his male organ along the outside and the opening of the woman’s organ. He can even use the tip to stimulate her external hot spot.

6. Thrust shallow. Along with varying thrust speed, the depth can be changed to extend duration. While stimulation of the top of the shaft and head is still immensely pleasurable, it may bring about release more slowly than full engulfment of the organ. Also, shallow thrusts are best for hitting her G-spot, so she won’t be likely to complain. Classic doggie style with shallow thrusts is great for a man’s ability to control thrust depth and hitting the G-spot.

7. Be more in the moment. Everyone has likely experienced the “race to the finish” mentality. It can be hard to delay that immensely pleasurable moment; sometimes, people fear that they won’t finish if they wait, so they let it happen early on despite an overall desire to go longer. Men can try to shift their perspective from seeing sensual activity as a means to finish to seeing it as an enjoyable experience at all its many possible stages.

Men aren’t likely to last longer if their skin is sore and chafed. That’s why it’s a good idea to use plenty of lube during solo play and sensual activity. It’s also wise to apply a male organ health crème (health professionals recommend Man1 Man Oil) after a man’s daily shower. A product with Shea butter and vitamin E can keep the skin is good condition and ready for action.

The Evolution and Refinement of V Engine Design

The Enduring Legacy of V Engines
Internal combustion engines have been propelling vehicles for over 150 years, with the designs proposed by Nikolaus Otto and Rudolf Diesel—both four-stroke engines—dominating the field due to their robustness, reliability, economy, and adaptability. These engines have been pivotal in the advancement of modern technology and the automotive industry, which remains a global economic powerhouse, directly and indirectly supporting billions of jobs.

The Rise and Challenges of V Engines
V engines, characterized by their two banks of cylinders arranged in a V-shaped configuration, have been lauded for their dynamic performance and mechanical efficiency. However, they also face significant challenges related to vibration and noise, primarily because the crankpin is acted upon by two pistons simultaneously, leading to complex forces and movements within the engine.

A comprehensive study on V engine dynamics was conducted by Florian Ion T. Petrescu and Relly Victoria V. Petrescu, who explored ways to optimize these engines’ performance. Their research, spanning from 1980 to 1986, revealed excessive vibration and noise levels that exceeded international limits. Various types of rubber shock absorbers were tested, with only a few models, such as those from Dunlop and ARO four-wheel-drive vehicles, showing promise.

Ultimately, the research led to a significant decision: the replacement of V engines with inline configurations or pseudo V engines, which offered lower efficiency but met the required standards for noise and vibration. This marked a decline in the use of V engines in passenger vehicles, although they continued to be used in tractors, trucks, locomotives, and high-tonnage ships.

The Quest for Quieter, More Efficient V Engines
The key to improving V engines lies in adjusting the constructive angle, alpha, which determines the kinematics and dynamics of the engine. By optimizing this angle, it is possible to balance the dynamic coefficients of the coupled pistons, leading to smoother operation with reduced noise and vibration. The ideal values for the alpha angle have been identified through dynamic analysis, offering a path to the synthesis of an optimal V engine.

Despite the challenges, V engines remain a symbol of power and performance, particularly in the racing world. High-performance vehicles, including those in Formula 1, often feature V engines due to their desirable characteristics.

The Future of V Engines Amidst Electric Shift
As the automotive industry gradually shifts towards electric vehicles, the role of internal combustion engines, including V engines, is evolving. While electric motors are becoming more prevalent, the majority of engines in use today are still internal combustion types, especially diesel and Otto engines. The transition to electric vehicles is constrained by the current methods of electricity generation, which often rely on the burning of fossil fuels, leading to continued pollution and high energy consumption.

Therefore, there is an ongoing need to improve thermal internal combustion engines, aiming to reduce fuel consumption and noise levels while maintaining their dynamic qualities. This pursuit ensures that V engines will continue to have a place in the automotive landscape, even as the industry embraces electrification.

Conclusion
The study of V engines, particularly their vibration and noise characteristics, has led to significant advancements in their design and application. While the shift towards inline engines was a response to the limitations of the time, ongoing research and development have opened the door to more refined and efficient V engines that can meet modern standards without sacrificing performance.

Funding and Research Acknowledgments
The research into V engine dynamics was supported by a contract with the Romanian National Center for Science and Technology and involved collaboration with various international partners, including the UK, USA, Canada, Germany, Italy, France, and Romania. Preliminary contracts were also established with BMW Group Germany and Mercedes Benz Daimler AG, Germany, highlighting the industry’s interest in this field.

References and Further Reading
For those interested in the technical details and historical context of V engines, a wealth of literature is available, including works by Christensen et al. (1999), Dahl et al. (2013), and many others. These studies provide insights into the evolution, challenges, and potential of V engines, contributing to our understanding of this enduring engine design.
