What is the effect of the foreskin on human sexual function?

Patient's question:

Since childhood, I have had excessive foreskin, and the glans cannot be exposed. As I grew older, the foreskin did not shrink, and during erection, it completely covers the glans, which is very embarrassing and uncomfortable. What kind of help do I want: What impact does the foreskin have on a person's sexual function?

Doctor's answer:

1、In cases of excessive foreskin, smegma accumulates between the foreskin and the glans, emitting a pungent, cheese-like odor. At this point, this unpleasant smell can render the most potent aphrodisiacs ineffective. Consequently, it leads to a complete loss of libido in both partners.
2、Impaired Sensation The nerves of the foreskin are far less sensitive compared to those of the glans. Once the tip of the penis is exposed, it can directly contact the vaginal walls, resulting in much sharper sensations. However, if the foreskin is too long, it may retract from the glans during intercourse and sometimes fail to return, preventing full contact.
3、Bacterial Growth Excessive foreskin can lead to smegma buildup, which serves as a breeding ground for bacteria. If the glans becomes infected, it may develop balanitis. Undergo circumcision.
