”Doctor, I’ve been circumcised, why do I still have premature ejaculation?” This question is often mentioned by patients. This question seems simple, but it is difficult to explain thoroughly. It is often difficult for doctors to have the time to explain it clearly to patients in an outpatient clinic. Today we will talk about this issue. 1. Why do you ejaculate? To understand the relationship between foreskin and premature ejaculation, first we need to understand the principle of ejaculation. In sexual activity, people receive sexual signals through various sensory organs such as sight, touch, smell and hearing. These signals are transmitted to the brain. When the excitement reaches a certain level and exceeds the threshold of ejaculation, then the brain sends out nerve signals to produce the action of ejaculation, accompanied by the pleasure of a strong orgasm. This is like blowing air into a balloon, and when the balloon reaches its limit size, it bursts. 2, why do people with long foreskin often ejaculate prematurely? The foreskin is a remnant of human evolution and development. In animals, it mainly plays a role in keeping the penis in place to some extent. In humans, however, the foreskin tends to become a burden to us. Many people have a long foreskin or even a stump, and when cleaning is not timely and convenient, they are prone to recurrent episodes of foreskin glansitis. We know that during normal sexual activity, the pleasure from friction between the glans and the vagina is the most intense. In the event of glansitis, the inflammation will give extra stimulation to the glans, which will lead to early ejaculation. This is the time when doctors often suggest to do a circumcision surgery, after the surgery foreskin glans is no longer easy to inflammation, then usually premature ejaculation will be good. 3, foreskin long will definitely premature ejaculation? Many patients believe that long foreskin will definitely lead to premature ejaculation, and even some doctors also hold this view. The above description shows that generally speaking, inflammation of the foreskin glans will lead to premature ejaculation. If it’s just a long foreskin, it will not necessarily lead to premature ejaculation. There is no inevitable relationship between the two, just as there is no inevitable relationship between wearing more clothes that tend to sweat and slipping on a rainy day. On the other hand, the source of sexual signals does not only come from the friction between the glans and the vagina. Sounds, smells, and other sensations are also sources of sexual signals that we receive. Furthermore, the speed of ejaculation also depends on a person’s ability to control sexual arousal. It’s like the balloon analogy we used earlier. When the balloon bursts, not only depends on the speed of blowing, but also depends on the size of the balloon itself. Clinically, we often encounter some patients who ejaculate before penetration, and this part of the patient, even if the foreskin is long, or even circumcised, is certainly not the cause of premature ejaculation. So, circumcision and circumcision are an important predisposing factor for premature ejaculation, but they are not the inevitable cause. On the other hand, if premature ejaculation does not improve after circumcision, you should try to find other possible causes or change your treatment strategy, rather than regretting the circumcision or losing confidence in the treatment.
