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 exposed, 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 harms of an excessively long 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, which needs to be cleaned promptly. In addition to excessive foreskin causing premature ejaculation, the glans mucosa is usually hidden under the foreskin, and the glans mucosa experiences less friction and stimulation than usual, making the nerve sensitivity of the glans mucosa overly sensitive. During sexual activity, when the glans is exposed after erection, the friction and stimulation between the glans and the vaginal wall can trigger premature ejaculation again due to the overly delicate and sensitive glans mucosa, leading to premature ejaculation.
