The penile frenulum is a fold of skin located underneath the glans penis that attaches it to the shaft. It connects the foreskin to the shaft if the male has one. The frenulum can be stretched when erect but retracts to expose the glans during an erection. Due to its position and sensitivity, stimulation of this area provides significant pleasure during sexual activity. For many men, a firm stroke along the frenulum will bring them to orgasm. However, some people are more sensitive than others. How is the penile frenulum structured?
The penile frenulum consists of several layers of tissue. At the base, where it attaches to the underside of the shaft, is connective tissue known as the dartos fascia. This tough layer holds the penis together and provides support. Below this is loose connective tissue called the tunica vaginalis testis. In between these two layers lies a thinner membrane called the corpus spongiosum. This is full of blood vessels and nerve endings which make it extremely sensitive. Nerves from the perineal body pass through the corpus spongiosum and send signals to the brain. What makes the penile frenulum so sensitive?
The highly innervated corpus spongiosum is what gives the frenulum such high levels of sensation. Nerves in this region carry messages about touch and temperature directly to the brain via the pudendal nerve. This means that any stimulation here is felt strongly throughout the entire genital region. Because of this, direct contact with the frenulum can produce intense arousal. The frenulum can be manipulated by hand or mouth to create varying degrees of intensity. It may also be stimulated indirectly during intercourse. Why should you care about your partner's penile frenulum?
Stimulating your partner's frenulum can add significant pleasure to sex. Whether you use your fingers, tongue, lips, or another part of your body, paying attention to this area will likely increase his enjoyment. If he has a foreskin, pull back on it to expose the glans and focus on the frenulum below. Vary the speed, pressure, and technique until you find what works best for him. Some men like more gentle strokes while others prefer firmer ones. Avoid pulling too hard as this can cause pain.
