How to insert the penis into the vagina

The most appropriate posture for the first sexual intercourse is the so-called normal position. The woman lies face up with her knees raised and legs spread, and the man lies in the middle with his elbows supporting his upper body, with the man on top and the woman on the bottom. The man's penis is not inserted downward, but parallel to the bed, and gradually moves into the woman's lower body. At this time, the woman's legs are stretched as far as possible, and the penis is inserted into the vagina.

If the male penis wants to grow longer, if it is over 18 years old, the corpus cavernosum has stopped growing and developing, and the possibility of growth is relatively small. And from the current clinical medicine, no drug can achieve the actual effect of lengthening, enlarging and thickening. Unless you can go to the hospital to choose to do penis lengthening surgery, it can generally increase by 1 to 2 centimeters. The penis of a normal yellow man is normal as long as it exceeds 9 centimeters when erect. The average length should be 8 to 16 centimeters after erection. Achieving this standard value can take into account the physiological needs of normal women.

If the penis is not inserted into the female vagina, it is not easy to get pregnant, because only after the male's semen enters the vagina and fuses with the egg cell to become a sperm-egg combination can pregnancy occur. If the patient does not have a real married life at this stage, there is no need to worry. However, one special situation must be ruled out. If the patient ejaculates outside the body, there is still the possibility of accidental pregnancy, because a small amount of semen will enter the vagina before the man ejaculates. If there are male sperm in this fluid, it will cause an accidental pregnancy.

If adolescents in puberty have a habit of long-term excessive masturbation or have a long foreskin, it will affect the normal growth and development of the penis and cause a short penis. First of all, you should immediately give up the habit of masturbation and consider surgical treatment for the long foreskin. In addition, you should increase the nutritional value of your diet and eat more high-protein foods, such as milk, eggs, seafood, and river shrimp, which can help the penis grow and thicken. If you reach adulthood, the short penis has become fixed and can no longer grow and develop. At this time, you can only consider improving it through surgical treatment.
