Erection and Ejaculation Part 2

Hello Dr.
Lin, thank you for taking the time to answer my previous questions.
I have a few more inquiries to ask you:
1.
Regarding the previous question about erectile issues, although there is pre-ejaculatory fluid during an erection and I mentioned feeling close to ejaculation without sexual stimulation, if I experience stimulation during a semi-erection, I ejaculate immediately.
Does this qualify as premature ejaculation? However, if I try to hold back, I experience nocturnal emissions.
Is this related to the sperm being full and the awareness before ejaculation?
2.
During sleep, I have tried to understand the phenomenon of penile erection.
Normally, with sexual or sensory stimulation, the penis can become erect, but if the stimulation is not continuous, it becomes flaccid.
Conversely, during sleep, even without the awareness of needing to urinate, the penis can remain erect for about half an hour.
Why is this the case?
3.
I previously suspected I had erectile dysfunction and took a quarter of a Viagra tablet, which allowed me to achieve ejaculation during the drug's effect.
However, the penis could still maintain a semi-erect state, and with further stimulation, it could achieve full erection.
If I do not take Viagra, it takes about an hour for the penis to become erect again, but the rigidity is not very firm.
Does this indicate that I have erectile dysfunction?
4.
I have noticed that the more Viagra I consume, the longer I can maintain a semi-erect state.
Is this normal? If I take it, the penis can remain semi-erect or achieve full erection even without sexual stimulation for about half an hour.
Would medications like Levitra or Cialis have similar effects?
5.
After ejaculation, if I continue to stimulate the glans or wipe away the semen and touch the glans, the sensation is difficult to describe.
Why is there such a significant difference in tactile sensation before and after ejaculation?
6.
Additionally, I have noticed that the darker areas of the glans have increased, but the distribution is uneven, particularly where I have frequently masturbated.
This reminds me of seeing middle-aged men's penises, where the glans appear gray or darker rather than a healthy pink color.
Is the color of the glans related to diet or prolonged friction?
Thank you.

Hello, sir: Thank you for your inquiry.
I would like to respond to your question and provide the following advice: There is no universally accepted definition of premature ejaculation.
Generally, it is recognized as a condition where a man is unable to delay ejaculation to satisfy himself or his partner.
However, your concern regarding masturbation makes it difficult to fit this definition.
The fact that you can maintain an erection for half an hour at night indicates that your erectile function is normal, and there is no need for further questions; you do not have erectile dysfunction, and you do not need to take Viagra.
Of course, the time to achieve another erection after taking Viagra is usually shorter due to the pharmacological effects of the medication.
I advise you, being young, not to rely on medication for enhancement.
Other medications in the same class will have similar effects, but individual responses can vary greatly, so it's best to experience it for yourself.
Lastly, the color of the glans is related to diet and long-term friction.
Wishing you peace and happiness!

More Info

Understanding erection and ejaculation is crucial for addressing common concerns related to sexual health. Your questions touch on various aspects of these processes, and I will address each one in detail.

1. Premature Ejaculation: The sensation of feeling close to ejaculation without significant sexual stimulation can indeed be a sign of premature ejaculation (PE). PE is characterized by ejaculation that occurs with minimal sexual stimulation, often before the individual wishes. If you find that you are unable to control ejaculation during sexual activity, it may be beneficial to consult a healthcare provider for further evaluation and potential treatment options. The phenomenon of "night emissions" or "wet dreams" is a normal physiological response and can occur when the body has an accumulation of sperm and seminal fluid, leading to ejaculation during sleep.

2. Nocturnal Penile Tumescence: The phenomenon of experiencing erections during sleep, known as nocturnal penile tumescence, is a normal occurrence. These involuntary erections can happen multiple times during the night and are not necessarily linked to sexual arousal or the need to urinate. They are part of the body's natural physiological processes and indicate healthy blood flow and nerve function in the penis. The duration of these erections can vary, and it is not uncommon for them to last longer than those achieved during waking hours due to the relaxed state of the body during sleep.

3. Erection Quality and Medication: The use of medications like Viagra (sildenafil) can enhance blood flow to the penis, facilitating erections. If you notice that you can achieve an erection with the medication but experience difficulty without it, this may suggest an underlying erectile dysfunction (ED). It is essential to discuss these symptoms with a healthcare provider, as they can help determine the cause of your ED and recommend appropriate treatments. The time it takes to achieve an erection can vary based on numerous factors, including psychological state, physical health, and the presence of any underlying conditions.

4. Effects of Different Medications: The duration and quality of an erection can be influenced by the type of medication used. Viagra, Cialis (tadalafil), and Levitra (vardenafil) all work by increasing blood flow to the penis but may have different durations of action and side effects. If you find that Viagra prolongs your ability to maintain a semi-erect state, it may be due to its pharmacological effects. However, it is crucial to use these medications as prescribed and to consult with a healthcare provider about any concerns regarding their use.

5. Post-Ejaculation Sensitivity: The difference in sensation when stimulating the glans (head of the penis) before and after ejaculation is quite common. After ejaculation, the sensitivity of the penis can decrease temporarily due to the release of hormones and changes in blood flow. This is a normal physiological response, and many individuals experience a refractory period during which further stimulation may not be pleasurable or may even be uncomfortable.

6. Changes in Penile Coloration: Variations in the color of the glans can occur due to several factors, including friction from masturbation, blood flow changes, and even skin conditions. Increased pigmentation in areas that experience more friction is common and can be influenced by individual anatomy and habits. If you notice significant changes in coloration or if there are any accompanying symptoms (such as pain or irritation), it is advisable to consult a healthcare provider for an evaluation.

In summary, many of the concerns you have raised are common and can be addressed through open communication with a healthcare provider. They can provide personalized advice and treatment options based on your specific situation. Remember that sexual health is an important aspect of overall well-being, and seeking help is a positive step towards maintaining it.
