Truthful facts about the penis can be hard to find. In What is the average size of a penis?, we give you information about the penis. There are so many rumors and conjectures about the penis that it has led to some amazing (or should we say long!) stories about the penis. There was the story of a man with a meter long penis that failed every time he got an erection. When you stop to think about it, nature really wouldn’t allow this to happen in the first place. Men fall asleep after sex, but that’s for different reasons.

The penis is shrouded in mystery in many cultures and is not something men feel they can talk about. Below, we answer some of the penis-related questions you’ve been afraid to ask.

1. What is the average length and diameter of a flaccid penis?

The average length of a flaccid penis is 3.5 inches and the diameter is 1.25 inches. Penile growth begins between the ages of 10 and 14. The penis first grows in length and then in diameter.

2. What is the average length and diameter of an erect penis?

The average length of an erect penis is 5.1 inches and the diameter is 1.6 inches. There is a built-in compensation. Those men with a smaller penis in the flaccid state will find that their penis will be the same size as the next man in the erect state due to a greater increase in volume when erect.

3. What is the average increase in volume from flaccidity to erection?

A man who has a non-erect penis that is considered small when flaccid will typically achieve an increase in volume of about 300 percent during sexual arousal. A man whose non-erect penis is of the largest size will probably achieve a 200 percent increase. That means that regardless of “shower” length, all penises will average 5.1 inches when erect.

4. What is the longest medically recorded erect penis?

The longest medically recorded penis measured an impressive 30 cm (12 inches) when erect and was 5.5 cm (2.25 inches) in diameter. A penis measuring 14 inches (35 cm) when erect was described in Everything You Ever Wanted to Know About Sex by Dr. David Reuben, however it was never independently authenticated.

5. How much blood is in the erect penis?

The average penis contains eight to ten times more blood than the flaccid penis. It is kept in the chambers of the penis. When a man suffers from erectile dysfunction, it is often due to a lack of blood flow to these two chambers.

6. Do we get erections at night and if so, how many?

Men get erections at night and research has shown that the atypical healthy man will generally have five erections a night, including the one he wakes up in the morning. The scientific name for these nocturnal phenomena is nocturnal penile tumescence.

7. What is the average time to a nocturnal erection?

Unbelievably, the average nocturnal erection lasts between 20 and 30 minutes. If you do the math, the average man gets a “bone-on” for 5-6 hours when he sleeps. We even think about sex more than every six seconds when we sleep, I guess.

8. If I had to replace my penis, how much would it cost to buy a working one?

In my research, the value varied, but a median figure would put a good member’s replacement figure at around £50,000 ($100,000). This figure is not openly available and won’t be showing up on E-Bay any time soon. Indecently, in my research I also found that you could get a penis-shaped swimming pool for $12,000. Which I thought was pretty reasonable.

In conclusion, the vast majority of men have the same penis size when erect and it is all mainly due to blood flow in the two chambers of the penis. It is this blood flow that can lead to erectile dysfunction in the male member.
