Doctor's answer:

There are several reasons that can cause male penile sensitivity and premature ejaculation. Men should pay attention to preventing the recurrence of the following causes:
1. Psychological factors: Frequently keeping the central nervous system in an unrestrictedly excited state and forming physical habits are important influencing factors for organic causes of premature ejaculation.
2. Genital organ diseases: A short frenulum of the penis can hinder full erection; chronic congestion and edema of the seminal colliculus can lead to rapid ejaculation with slight sexual stimulation.
3. Differences in physical fitness: The erection response of the corpora cavernosa in premature ejaculation patients is faster than in non-premature ejaculation individuals.
