1. Is the penis the bigger the better
The bigger the penis, the better. Because some penises are too large, which is a signal of some diseases. For example, there is a tumor in the lower part of the thalamus or pituitary gland, or there is brain injury, viral encephalitis and other reasons that cause excessive secretion of gonadotropin; Another example is that testicular lesions cause excessive testosterone secretion. These factors will cause excessive growth during penis development. Therefore, if the penis is too large, you should be alert for the above diseases.
2. Normal penis length
Through nearly 30 years of research, the International Men's Health Organization (MTD) concluded that:
Normal penis length M=(height T-105) * 0.618/3.14 (cm); Normal penis diameter D=M/3.14 (cm) (Europe and America=Asia/1.414/0.618) cm; The penis length standard: less than 5 cm when weak.
Some people have done a survey on the satisfaction of penis length. Nearly seven adults "care about the size of penis very much", and nearly two of them hope that "there is a panacea that can make it immediately bigger". Among the surveyed people, nearly six adults believe that the "second" should be 14-18 cm long.
But the actual situation is not as ideal as men think. According to the data, the average length of male penis erection in the United States is about 15 cm, while that in China is about 13 cm.
3. Where to measure the length of penis
The length of the penis should be measured from the pubic symphysis above the penis to the top of the penis head. Here is a common method for doctors:
Measurement of the length of the non-erect penis: at room temperature of 18 ℃, take an upright position, lift the penis at 90 ° to the body, and measure the length from the pubic symphysis above the penis to the top of the penis head with a ruler.
Measurement of erectile penis length: take an upright position, hold the penis head with your hand and pull it forward until it cannot be extended. Measure the length from the pubic symphysis to the penis head with a ruler (the length after pulling is basically the same as the length of erection), and it is normal to be greater than or equal to 8 cm.
Men with smaller penises don't need to care, as long as the method of making love is appropriate, it will not affect sexual life.
1. Bags under the eyes: Generally speaking, if the bags under the eyes are tight and moist, it means excellent sexual ability. Most of the men with baggy eyes, sagging eyes and dirty looks are "strong outside but weak inside".
2. Clean front teeth: according to traditional Chinese medicine, teeth belong to the kidney. When the front teeth are clean and bright, the body will be healthy and vigorous; On the contrary, the sexual ability of men with weak blood is of course not good.
