The genitals are the most important organs of human beings and have a decisive influence on their reproductive ability. The genitals of men and women are completely different. They are very different in appearance. For example, the most obvious point is that men have a protruding genital organ, which is the penis. Women do not have this. Why do men have penises? Let's take a look at the explanation below. It is an important male sexual organ that has the function of sexual intercourse, urination and ejaculation. The penis is mainly composed of two penile corpora cavernosa and one urethral corpora cavernosa, which are covered with basal fascia and skin. It is divided into three parts: root, body and head. The rear part is the root of the penis, which is attached to the inferior ramus of the pubic bone, the sciatic ramus and the urogenital diaphragm; the middle part is the body of the penis, which is cylindrical and hangs down in front of the pubic symphysis; the front part is enlarged as the glans penis, with a sagittal cleft at the tip of the head called the external urethral orifice, and there is a ring-shaped groove at the junction of the head and the body called the penis neck or coronal sulcus. Organizational structure The blood supply to the penis comes from the dorsal penile artery, a branch of the external iliac artery. During sexual arousal, the three branches of the dorsal penile artery and its arterioles dilate, increasing blood flow; the arteriovenous communication branch is blocked, venous return decreases, and the cavernous sinus becomes congested, causing penile erection. The head of the penis has abundant nerve endings, so the frenulum of the penis, the coronary sulcus, and the area around the urethral opening are particularly sensitive to external mechanical stimulation. The afferent nerve of sensory sensation is the dorsal penile nerve. After reaching the low sexual response center of the sacral cord, the efferent parasympathetic nerve innervates the penile vascular smooth muscle and changes the vascular state. Pathological changes in the penile blood vessels and nerves can affect mating function. The satisfaction during sex has nothing to do with the length of the penis. The key is whether there is love and passion. Real excitement is based on a harmonious relationship and love. Just make sure there is enough foreplay and a variety of positions. As the saying goes, every inch has its own merits and demerits. As for whether a woman likes it or not, it mainly depends on whether you can satisfy her sexually. This mainly depends on the skills and tacit understanding between the two parties. Men have different lengths and can use different positions and skills to make women get the most perfect sex. |
