Scientific theory behind a Boner: 

Before understanding about ‘erection feeling’, let’s discuss what an erection actually is. 

Erection is the result of blood flowing into the spongy tissues of the penis. These tissues are known as corpora cavernosa. The veins that normally drain blood constrict. Due to these two factors, penis becomes upright and firm. 

Important role players in this process: 

1. Nerves: Brain and genital area gets signals through nerves to trigger arousal. 
2. Hormones: Hormones named testosterone is very important for libido and sensitivity. 
3. Blood vessels: They collect blood to form rigidity. 

So, this is all about the biology behind erection. Now, we will talk about sensations. 

How does a Boner feel? 

Here, we will explain the common themes about physical sensations based on physiological research and anecdotal reports. 

1. Pressure: The very obvious thing in erection is pressure as penis gets filled with blood. But if it feels heavy, different from the usual flaccid state, then it’s very noticeable. 
2. Warmth: You may feel warmth because of the increased blood flow. This is the part of the arousal response. 
3. Sensitivity: During erection, even a light touch can feel intense because nerve endings become more reactive. That’s why penises become hypersensitive. If it stays without release, it can be uncomfortable for the man. 
4. Psychological overlay: An erection is not always about physical sensation only. It’s linked with the brain as well. Physical feelings like excitement, anticipation or arousal can make this experience intense. That’s why erections are common during sleep or even without any conscious sexual thought. 

Factors that can change feeling of erection: 

You must know that erection doesn’t always feel the same. Many factors can influence sensation. These factors include: 

1. Age: Young men get stronger and frequent erections. 
2. Hormonal levels: If you have low testosterone, erection frequency and intensity can be reduced. 
3. Mood and mental state: Chronic stress, fatigue, sadness can alter feelings. 
4. Physical health: Nerve damage or circulatory issues can alter feelings. 

So, if you know someone with different experiences, it’s normal. 

Why does knowledge matter? 

You must understand that erection is normal but changes in firmness, timing and even feelings are not normal. So, you must have knowledge about it to get medical assistance whenever required. Moreover, it helps to avoid some embarrassing moments with your partner. 

Myths and facts: 

There are some common myths and facts about erection that need to be cleared. 

1. Myth: Erection only happens due to sexual arousal. 

Fact: No, this is not true. Erections can happen spontaneously, even during sleep or any random time without any sexual thought. 

2. Myth: Morning erections are a sign of sexual activity during sleep.

Fact: This is a very common myth but the reality is that morning erections occur because of hormonal surges or relaxed muscles during REM sleep. 

3. Myth: Bigger the penis, harder the erection. 

Fact: No, penis size doesn’t determine the erection’s firmness. It depends on the blood flow and your tissue health. 

4. Myth: No erection means psychological issues. 

Fact: Erection can be affected due to poor circulation, hormonal disturbance or nerve damage etc. It doesn’t always mean mental health issues. 

5. Myth: Frequent erections mean higher sexual desire. 

Fact: Erections can occur without any sexual desire. These are the parts of the natural physiological process. 

6. Myth: Erectile dysfunction only affects older men. 

Fact: No, several other factors like injury, age, stress, anxiety, medical conditions are equally responsible. 

7. Myth: Only a touch can trigger erection. 

Fact: No. It can be triggered by mental, emotional or even visual stimulation. 

8. Myth: An erection should always be fully rigid. 

Fact: Even partial erections are equally normal. 

Overall sensory journey: 

Now, you must be thinking about exactly which part of the penis is most sensitive. 

So, your answer is glans (head) because its ending point of nerves and the entire shaft contributes to sensitivity. This tip of the glans is known as the peak zone for sensation but it varies by individual. 

You need to understand the overall journey to understand sexual health and boner. Here is a step-by-step guide to understand this journey: 

1. Initial awareness: This is a feeling of warmth, pressure and tingling signals that blood is flowing through tissues. 
2. Expansion: Then penis starts swelling and firm with hyper sensitive glans. 
3. Heightened sensitivity: Even a very soft touch may feel intense at this moment. It’s their body’s response without even thinking about it. 
4. Tension: Muscles contract and then penis starts feeling heavy. If it’s a regular pressure, then it’s completely natural. But remember, abnormal heaviness is not normal. 
5. Peak sensation: During the peak moments, penis gets fullness, warmth and psychological arousal. 

This journey can last from a few minutes to half an hour depending on your activity and arousal levels. 

Conclusion: Overall, you must know that boner doesn’t always mean a funny topic. It’s a mixture of biology, psychology and sensation. A deep understanding of this topic avoids awkward moments with your partner as it’s a powerful health indicator. Erections are unpredictable and a normal part of life so its knowledge can help you to get sexual self-awareness to avoid myths about this topic. 

So, next time, if you get boner at an unusual time, just remember that your biology is working perfectly even during this inconvenient time. But if it’s abnormal, talk to your doctor to avoid any unwanted situation.
