Physiological causes of sexual pain

There are many reasons for sexual pain, including various diseases of the reproductive organs and urinary system, congenital malformations, etc. Typical lesions are endometriotic nodules on the uterosacral ligament close to the posterior fornix of the vagina, intrapelvic inflammation and peritoneal organ adhesions. When the penis is inserted and touches the nodules, the friction with the vaginal mucosa causes the peritoneum to shake and pull the organs, causing pain.

In addition, specific vaginal allergies, such as allergies caused by the use of contraceptive tools, can also cause pain. The first intercourse after marriage will tear the hymen and expand the vaginal opening, which may also cause pain and slight difficulty in intercourse in the first few days. The excitement of a newlywed couple and the busyness and fatigue that comes with it can also make intercourse incompletely satisfactory, so it usually takes 3-4 weeks after the wedding to achieve satisfactory intercourse.

Hasty intercourse, that is, before the woman's sexual excitement is fully aroused, the front of the vulva lacks swelling and lubrication. Inserting the penis at this time, or inserting it a little violently, often causes temporary discomfort and pain. Then, sexual excitement will be suppressed, and with the thrusting and friction of the penis, the pain may increase, especially in the highly sensitive clitoris area. Because it has rich blood vessels and nerve tissue, if it is not excited and dry, it will not only cause pain, but also produce an unbearable feeling of disgust psychologically.

In the absence of organic lesions, sexual pain is mainly caused by insufficient vaginal lubrication. There are two main reasons for insufficient sexual arousal: one is insufficient preparation for intercourse, that is, insufficient flirting actions such as hugging, kissing, and caressing as mentioned above; the other is intercourse anxiety, fear, lack of concentration, and depression and unhappiness caused by work and life.

To sum up, the above content describes the physiological causes of pain during sexual intercourse, which can help people better understand pain during sexual intercourse. Once people have pain during sexual intercourse, they should seek timely treatment and maintain local hygiene.
