The penile frenulum connects the underside of the glans to the shaft and is highly sensitive. This small piece of skin can be found at the opening of the foreskin, where it connects to the coronal sulcus. It is also known as the preputial commissure or simply as the "banjo string." The frenulum serves several important functions. First, it protects the glans from damage during intercourse. Second, it helps prevent premature ejaculation by providing additional friction against the vaginal walls. Third, it increases sensitivity during sexual activity. When stimulated, the frenulum produces lubrication that enhances pleasure. Finally, it can become more sensitive when pulled on during foreplay oral sex. Penile anatomy
The penis consists of three main parts: the root, body, and head. The root extends into the pelvic cavity and attaches to the pubic bone; the body runs downward toward the scrotum; and the head is the enlarged tip at the end of the penis. The glans penis, or head, contains thousands of nerve endings that are densely packed in clusters called corpus spongiosum. These nerve endings are responsible for sensations of pleasure during sexual arousal. Just below the glans is a band of tissue called the corona, which covers the head and surrounds the urethra. The frenulum lies just below the corona and connects it to the base of the shaft. Frenular variations
In some men, the frenulum may be longer than usual and extend beyond the base of the glans. This is known as a long frenulum or "banjo string" (or "lariat"). A shorter frenulum is called a short frenulum or "tight band." In rare cases, there may be no frenulum at all ("frenulectomy"). Men with these conditions may experience painful intercourse due to friction against the vaginal walls. Other men may have a split frenulum, where the skin is torn or stretched along its length. Frenular function
As mentioned earlier, the frenulum serves several important functions. First, it protects the delicate glans from injury during intercourse. Second, it helps prevent premature ejaculation by providing additional friction against the vaginal walls. Third, it increases sensitivity during sexual activity. When stimulated, the frenulum produces lubrication that enhances pleasure. Finally, it can become more sensitive when pulled on during foreplay oral sex. Frenular care
The frenulum is a delicate structure and should not be manipulated excessively. However, over time, it can thicken or become callused. Men who frequently engage in masturbation or use vibrators may develop callouses on their frenulums. These calluses are harmless but may reduce sensitivity during sexual activity. To avoid this, men should gently massage the area with lotion before sex. If they have a split frenulum, they should avoid rough contact with the area. If the frenulum becomes infected (balanitis), it may need medical treatment.
