Patient's question:
After my penis has been erect for a long time, my testicles or something near them will feel, and there is also pain when pressing the base of my penis with my hand. Lying down is the only way to relieve it. This situation occurred when I was dating my girlfriend 2 years ago, and I am only 20 years old now. What could be the reason for this?Doctor's answer:
The hardness of the penis can be affected by excessive mental tension or too frequent sexual activity. As for why pain may occur, you should know: under the influence of sexual stimuli such as romance, hugs, kisses, or the waltz, the brain's sexual center is excited through sensory reflexes like vision, hearing, and touch. The brain then transmits this excitement to the spinal cord. On one hand, this leads to penile erection; on the other hand, it increases the secretion of glands and ducts in the reproductive system. A large amount of secretions (mainly prostatic fluid, seminal vesicle fluid, etc.) accumulates in the seminal vesicles, vas deferens, epididymis, and urethra. If sexual activity occurs during this time, these secretions form semen along with sperm and are expelled. However, if sexual intercourse does not take place, these secretions cannot be expelled, resulting in a state of "fullness without overflow." This causes passive expansion of the prostate, vas deferens, and epididymis, stimulating the nerves of these organs and reflexively causing.
