What does a normal male penis look like?

The penis is an important reproductive organ of men, often referred to as the "lifeline" of men. However, most men do not know much about their "lifeline". What is the normal length of a man's penis? What is the normal state of a man's penis? What is the normal state of a man's penis when he ejaculates? The following is an analysis of these doubts about the normal penis of men:

What does a normal man's penis look like?

The length of a normal adult male penis is: the normal length range is 4.9-8.6 cm, the average is 6.55 cm, the longest is 10.6 cm, and the shortest is 3.7 cm. The average length of the penis of male college students aged 16-40 was measured, and the average circumference was 8.17 cm; the average length of the penis was 13.34 cm, which is similar to the calculated erection length of 13.08 cm, so the length of the penis can be considered to represent the length after erection.

Second function

1 Sexual intercourse

Sexual intercourse broadly refers to the mating behavior between male and female animals of different species, which requires the participation, stimulation and excitement of reproductive organs. From a biological perspective, the purpose of sexual intercourse is reproduction.

Sexual intercourse refers to the act of a man inserting his penis into the vagina or anus, and ejaculating due to arousal to transport sperm. During sexual intercourse, the man's penis becomes erect, and the woman's vagina becomes lubricated due to arousal, making it easier for the penis to enter the vagina.

2Urination

Urinating is the process by which urine is produced by the kidneys and temporarily stored in the bladder through the ureters. When a certain amount of urine is stored, it is excreted from the body through the urethra multiple times. Urinating is a complex reflex activity controlled by the central nervous system. The penis is the outlet for urination in male animals.

3 Ejaculation

Ejaculation is a reflex action of male animals to eject semen during sexual intercourse. Human ejaculation is a series of coordinated actions of various parts of the reproductive system, and semen is ejected from the penis. It includes a two-step spinal reflex, the primary center is in the lumbar sacral spinal cord, and its sensory impulse is transmitted by the touch receptors of the glans penis.

Ejaculation is a complex process that includes erection, ejaculation, ejaculation and orgasm. Erection is due to the swelling and hardening of the penis, and its primary nerve innervation comes from the sacral nerve complex and the pelvic visceral nerve or erectile nerve.

The above is an explanation of the normal male penis. As long as it is within the normal range, there is no big problem. Some men feel inferior and anxious because of the problem of short penis. In fact, short penis has no direct impact on men's sexual function. As long as the penis can erect normally and achieve sexual intercourse, there is no problem.
