From foreskin to ejaculation, a comprehensive analysis of male health and related issues in male sexual function.

Will having a long foreskin affect the quality of sexual life?

Generally, a long foreskin does not require circumcision. However, circumcision is necessary in the following situations:

(1) The glans is completely covered, and the foreskin cannot retract to the coronal sulcus during erection.

(2) During erection, the glans is completely covered and very tightly constricted, and the foreskin cannot retract to the coronal sulcus.

(3) During erection, although it can retract to the coronal sulcus, it cannot automatically retract to its original position to cover the glans after the erection subsides.

(4) Although the foreskin is too long, it does not hinder erection in any way; it can retract to the coronal sulcus and move freely up and down, so circumcision is not necessary. However, dirt often accumulates there, and no matter how much you clean it, it cannot be completely removed, causing an odor and repeated infections.

(5) During intercourse, when the penis is erect, the foreskin retracts to the coronal sulcus. However, after intercourse, once the erection subsides, the foreskin becomes constricted at the coronal sulcus, causing pain and bruising. In severe cases, it can even lead to paraphimosis, also known as phimosis, which is not only very painful but can also cause permanent damage.

Basically, as long as the above-mentioned conditions do not occur, it will not hinder the enjoyment of sexual life. Of course, unless personal hygiene habits are poor, allowing dirt and grime to accumulate under the foreskin and ignoring it, even without phimosis, a sexual partner will find it repulsive.

How high should the penis rise during an erection to be considered normal?

Most people believe that the penis must be raised upwards during an erection to be considered normal, and that only elderly men with low sexual ability will not be able to achieve an erection.

Some people believe that when the five fingers are spread, the angle of the thumb's spread corresponds to the erection angle of a 10-year-old boy, the index finger to a 20-year-old boy, and so on, with the middle finger representing a 30-year-old, the ring finger a 40-year-old, and the little finger a 50-year-old and older.

Basically, this claim has no medical basis and should not be taken as gospel. Furthermore, penile shape varies from person to person, and naturally, the angle of erection differs from individual to individual.

First, it's important to understand that the mechanism causing the penis to point upwards is ligament contraction, which lifts the penis. The sympathetic nervous system controls this contraction; therefore, the more sensitive the sympathetic nervous system, the greater the upward angle of the penis.

However, the sympathetic nervous system also controls ejaculation. Therefore, the more sensitive the sympathetic nervous system, the easier it is to achieve an erection, which immediately points upwards, leading to ejaculation after a few strokes. After ejaculation, the penis immediately becomes flaccid, meaning lower stamina.

Men whose erections don't rise too high, indicating less sensitive sympathetic nerves, also tend to ejaculate less quickly, suggesting they have greater stamina.

Furthermore, the success of sexual intercourse is not related to the angle of the erection. Even those with low erection angles or declining erectile function can achieve mutual satisfaction through various techniques and tender, considerate treatment.

What causes less noticeable pleasure during ejaculation?

In male-female sexual intercourse, less noticeable pleasure during ejaculation may be related to the following:

(1) Endocrine factors: Male sexual function is maintained by androgens. Low levels of sex hormones due to various reasons can reduce libido and diminish pleasure.

(2) Reproductive organ diseases: Conditions such as phimosis, paraphimosis, urethritis, prostatitis, and seminal vesiculitis can worsen symptoms during intercourse, reducing sexual pleasure.

(3) Medication: Drugs such as sleeping pills, sedatives, and antihistamines can decrease nerve sensitivity, thus affecting pleasure.

(4) Other factors: Frequent sexual activity can lead to excessive fatigue of the sexual nerves. Being too hasty or rough during sex, insufficient foreplay, vaginal dryness, odor, illness, painful intercourse, or long-term frigidity in the woman can also reduce sexual pleasure. Furthermore, chronic illnesses, poor physical condition, and depression can also affect libido and pleasure.
