What is a short frenulum?
The foreskin is a membranous line, more or less thick, which is located under the glans and connected to the skin of the penis.
Typically, a short frenulum causes traction of the glans down. It does not really prevent the foreskin from retracting. A too short frenulum is a real handicap for young adults during sexual activities. Indeed, if a rather narrow brake is fragile and when the erection is strong enough, it can cause pain during penetration or even premature ejaculation. Moreover, the frenulum can crack or even tear with bleeding.
Discomfort from a torn frenulum may last for a few days after more intense sexual activity. It eventually heals after a few days of abstinence. But, unfortunately, often, the dynamic is repeated when resuming sexual activity.
