Scientific measurements

Men are probably not as concerned about height as they are about Ding Dinglai, and there are many encounters with bayonets between boys from junior high school to college. But how exactly do you measure the length of a tintin? Today's Friday science will be briefly introduced, especially note, length is not the key, skill, hardness and durability are very important.
The length of the yin stem is a problem that many men will care about, and some men even have a psychological yin shadow because they are worried that the yin stem is not long enough, which affects the sex \ life. In fact, there are individual differences in the size of the yin stem, so there is no need to compare them too much. The length of the penis stem in the non-erect state of young and middle-aged men in China is between 4.5 and 8.8 cm, and the average is 6.5 cm.
How do you measure the length of the yin stem? Interested readers may wish to try to test it at home, but pay attention to two states.
The first is the measurement of the length of the non-erect stem: the room temperature is not lukewarm or hot, take a standing position, lift the yin stem to the body at 90°, and measure the length of the pubic symphysis above the pubic stem to the top of the head of the yin stem with a ruler.
The second is the measurement of the length of the erection stem: similar to the first one, but pay attention to the natural erection state, do not overstimulate and pull the yin stem, generally greater than or equal to 10 cm is normal. Men who are overweight have a lot of belly fat, and some of the pubic stems are "hidden" in the fat, and there will be errors, so you can use your hand to measure the fat in the lower abdomen.
Finally, I remind everyone that the length of the yin stem is not a golden indicator to measure the man's sexual \ happiness index, as long as the erection is normal and there is no premature ejaculation, you don't have to care too much.
