Patient's question:
Now that I'm in college, when I take a bath with my classmates, I compared it and found that my foreskin is a bit long, with the entire glans completely covered. At other times, even when erect, the glans cannot be seen, and it takes a lot of effort to pull the foreskin back to reveal it smoothly. At the end of the pull, there is still some pain. I'm worried that this excessive foreskin might affect my health in the future. What are the dangers of an excessive foreskin?Doctor's answer:
The hazards of excessive foreskin are prone to accumulating smegma. If white substances grow inside the foreskin, it may be smegma and needs to be cleaned promptly. In addition to excessive foreskin causing premature ejaculation, the glans mucosa is usually hidden under the foreskin, with less friction and stimulation than usual. This makes the glans mucosa overly sensitive. During sexual activity, when the glans is exposed upon erection, friction and stimulation between the glans and the vaginal wall can trigger premature ejaculation due to the excessive delicacy and sensitivity of the glans mucosa, leading to premature ejaculation.
