How long is endurance normal

1. Problem analysis: Hello, men's normal sex life is Asian, Chinese people generally in 30 minutes, but it also varies from person to person. Young, energetic people have longer sex life
suggestions: indivials can have about half an hour or an hour. People with kidney deficiency or sexual dysfunction will have less time. People with premature ejaculation can ejaculate in 10 minutes. If you have sexual dysfunction, please see a doctor in time

2. The normal range is 5 to 30 minutes. Insufficient or excessive length is abnormal. Please accept

3. It's completely normal. You should be happy

4. Healthy men's sex time
can be at least more than 1 minute, with an average of about 3 minutes. If there is an appropriate pause time, coupled with the change of consciousness and delayed ejaculation, the ration of sexual intercourse can be 10 minutes or even 30 minutes, sometimes even longer
men's sexual intercourse ability in middle age and menopause
when men are 50-60 years old, their sexual desire is not necessarily decreased, or even somewhat hyperactive. Sexual ability is maintained even to the age of 60-70
after 40 years old, it is better to have sex no more than once every 4 days, and after 50 years old, it is better to have sex once a week. This value is just a limit value, not a conclusion
what is normal sexual ability
can give enough sexual stimulation. And the male penis into the female vagina. It's the first stage of intercourse
the reasonable scale of men's sexual ability is 5-10 minutes. In this period of time, the efficiency of men's pelvic advancement can be as high as 50-100 times / minute. The frequency of sexual behavior is greatly influenced by external factors, so it is difficult to judge the strength of qualitative ability. It's normal for a man to have sex between once a week and twice a day.

5. Indeed,
generally, I don't take a condom. If I take it for 15-20 minutes,
about 30 minutes,
- --- the above time is not foreplay ~

in fact, it's just this kind of enrance... As for the national football team that doesn't shoot for 90 minutes

6. It depends on people. We can't generalize.. Thank you. It's a long time for foreign countries

7. Calculation ability is the basis of primary school mathematics. Almost all kinds of exercises and examinations involve calculation

to a large extent, it determines the test results of mathematics. If the students have poor computational ability, it is difficult to accurately and timely calculate the correct answers in limited time, which leads to endless questions. Even if they finish the questions in a hurry, there will be problems with low accuracy. How can children's test results be improved

In order to improve the calculation ability of primary school mathematics, we should start from the following aspects:

1. In the process of calculation, we should properly use the law of exchange and combination of addition to simplify calculation:

example 1. Calculation:

(1) 53 + 36 + 47

solution: the original formula = 53 + 47 + 36

= 100 + 36

= 136

(commutative law)

(2) 24 + 44 + 56

solution: original formula = 24 + (44 + 56)

= 24 + 100

= 124

(Law of combination)

2. Learn the skill of "rounding up" in the process of calculation:

example 2. Calculation:

(1) 52 + 69

solution: the original formula = (21 + 31) + 69

= 21 + (31 + 69)

= 21 + 100

= 121

263+18+19

solution: the original formula = (60 + 2 + 1) + 18 + 19

= 60 + (2 + 18) + (1 + 19)

= 60 + 20 + 20 = 100

358+58+58

solution: the original formula = (58 + 2) + (58 + 2) + (58 + 2) - 6

= 60 + 60 + 60-6

= 180-6

= 174

Change the operation order in the process of calculation:

example 3. Calculation:

(1) 57-18 + 19

solution: the original formula = 57 + (19-18)

= 57 + 1

= 58

(1) 23 + 20 + 19 + 22 + 18 + 21

solution: the original formula = (20 + 3) + 20 + (20-1) + (20 + 2) + (20-2) + (20 + 1)

= 206 + (3 + 0-1 + 2-2 + 1)

= 120 + 3 = 123

note: the six numbers are close to 20, and 20 is taken as the reference number

Calculation:

(1) 1999 + 999999

solution: the original formula = (1000 + 999) + 999999

= 1000 + (999 + 999999)

= 1000 + 999 (1 + 999)

= 1000 + 9991000

= 1000 (1 + 999)

= 10001000

= 1000000.

when doing questions, you should practice more, use oral and mental arithmetic, and use more when mastering skills, so that your computing ability will be improved

8. It's all before! It used to be normal to have a strong enrance, but now it's normal to have a weak enrance

9. I'm not sure about your weight. In fact, this is very important. If you are overweight, you can't exercise yourself according to the general way of running, otherwise it will easily bring another burden to your body
after reading your introction, I feel that your condition after running belongs to the normal category. My suggestions are as follows:
1
2. The speed should not be too fast, and there is no need to accelerate halfway or run at full speed. Even speed jogging is the best for the body, and the effect of exercise is also the best
3. As for the time of running, I think it's more appropriate to have a light panting, fever and slight sweating. If you feel you can't breathe, take a rest for a while. If you feel your legs are sore and swollen, you will stop running
4. Keep your running posture straight, walk at an appropriate frequency, swing your arms actively, breathe at a constant speed, and take a deep breath
5. With your exercise, please improve your diet structure. Meat should be enough. Usually, eat more fruits and vegetables and eat 70% of your meals. Don't run for an hour after meals
6. Please warm up before running and stretch after running
