Revealing secrets: physiological knowledge that men and women must not know

Whether you have had sex or not, you must understand the physical knowledge of men and women. These physiological knowledge will allow you to adapt quickly in the future sex life, so that there will not be too much embarrassment or even sexual mistakes.
The physiological knowledge that a man must know
What is a man's sexual function if defined by numbers? I believe that many men and women will be interested in this. How many points can you get when your ability turns into a number?
The age of 18 is the "peak" age of male sexual function, because male hormone secretion is the most exuberant at this time. However, due to lack of experience, men of this age group may not have the best sexual performance.
5 calories. A single ejaculation is equivalent to a mouthful of sputum, and its calories are about 5 calories. "this is high in calories because semen is rich in fructose and biological enzymes." Mark Goldstein, professor of colonization and urology at Cornell University in the United States.
45 km / h refers to the speed at which men ejaculate. Sperm rush forward at a "medium speed" from the vas deferens to the glans, but once they enter the vagina, they slow down sharply, as if thousands of troops drove into an one-way lane from four lanes at the same time. In general, sperm need to crawl for 5 minutes to reach the cervix, and then it takes 72 hours to "meet" with the egg.
L. Men ejaculate each time about 2-7 milliliters, a lifetime can produce liters, many of which are prostatic fluid.
Ten hours. Swiss research has found that most men have fully recovered their physical functions about 10 hours after having sex, and the so-called "you can't sleep with each other before the competition" is a complete fallacy. Of course, with age, some men's recovery time will be appropriately extended, taking about 12 hours.
15 centimeters. After 90% of men have an erection, their penis is about 14-16 cm long, mostly 15 cm. However, if a man is obese or overweight big black ass , his penis will be much shorter.
The physiological knowledge that a woman must know.
Oversized visitors "she" can also handle it.
The vagina will enlarge with the increase of sexual desire. "the vaginal wall is like a pleated skirt, which opens when sexual desire is aroused, making the vagina 2 or even 3 inches in diameter. At the same time, the vagina will stretch to 6 inches. If he is not big enough, the vagina can also automatically adjust its size to ensure that it gives you the most comfortable enjoyment.
There is a happy organ in the depths of "her".
About an inch of the vagina, there is a small area called the G-spot. "to find your G-spot, you can slowly explore with your fingers-grope along the vaginal wall and you will find a coin-sized fold that is quite different from a smooth vaginal surface. If you gently rub this part, you will obviously feel that the sexual desire in the body is greatly aroused my old ass , and if you continue to touch it, you can quickly reach the best part. "
Pubic hair exists for a reason.
The hair around the vagina can reduce the impact of sex and reduce friction against the skin. At the same time sexshop , they are also attractive "aphrodisiac", at least during the caveman period-vaginal hair helps collect the smell of female hormones to attract other members of the opposite sex.
The "she" of giving birth increases fivefold.
Usually, our vaginas are no more than an inch in diameter. But before the baby is born, the vagina unexpectedly expands to 4 to 5 inches wide to ensure that the baby's head can pass through. But don't be alarmed. Six weeks after giving birth, the vagina returns (or almost) to its pre-pregnancy size. Men like the touch of "her"
How does a man feel when he is in his vagina? I think many women have thought about this question. Men say they are crazy about the warm, smooth touch, and they feel really contained and completely surrounded by your soft vagina-an absolutely indescribable experience.
Some women don't have vaginas.
About one in 4000 to 5000 baby girls is born without a vagina, and she probably doesn't have a uterus either. Fortunately, surgery can reproduce their vaginas, and their future sex life will have little impact.
She also likes to exercise.
Exercise in the gym can bring you a flat belly girl butt , strong arms and a well-proportioned figure. So it's not surprising if we say that giving her vagina exercise will make her healthier. Kegel training is a more common training method, through which you can exercise the muscles in the vagina, so that you can more fully enjoy the best part of sex. After months of Kegel training, you can better experience excitement during sex, and tight vaginal muscles will bring you a more enjoyable experience than ever before.
