Why is it important to state all of this ?

Just correcting the misconceptions that people have which have been passed around for far too long.

On no, this thread has made a comeback again, with it's inaccurate information. Reputable scientific studies show no appreciable average penis size differences between various countries or ethnicities. For instance a scientific study done in Nigeria showed an average size 0.2 inches smaller than a scientific study done in South Korea. Nearly every scientific penis size study has found an average erect length between 5.1 and 5.5 inches bone pressed and an average erect girth between 4.5 and 4.7 inches taken at the mid-point of the shaft. Even those averages may be larger than the true average, due to the potential reluctance of smaller men to have their penises measured by medical staff, whereas a larger man might be more willing to show up for the study in order to show off.

The average human penis is nowhere near as large as people expect it is. Any survey that relies on self reporting ends up biased by factors like perceived ideal size (which is often skewed by pornography) and trolling. Studies show that most people think the average penis size is larger than it is, with most people thinking the average is between 6 and 6.5 inches, but the Brazilian Journal of Urology actually compiled the data from 17 scientific penis size studies from around the world, what they found is that only 5 out of 100 men have a penis longer than 6.3 inches.

There is also a general belief that women prefer larger penises than they actually do. There was a study done where they 3D printed various penis like dildos with no measurements written on them and asked women to pick up the one they found to be the ideal size for a one night stand and the one they found to be the ideal size for a long term relationship. The average of the casual sex penis was 6.4 inches long by 5 inches girth, while the average of the long term relationship penis was slightly smaller at 6.3 inches long by 4.8 inches girth. While both are larger than the average man, it's not a huge difference and the ideal is certainly not the 8 inch by 6 inch meat bat that watching pornography would make you think the majority of women like.

Yeah but why ? At the end, the only Richard they're caring about it their own

Because those misconceptions can cause significant harm to the self image of men. Western culture in particular is bombarded by pornography of top 1 percentile guys satisfying women for long stretches of time, then there is the porn genre of women making fun of "small penis" guys, but even those guys aren't small, they are just porn small, the vast majority are well above the actual scientific average. Seeing nothing but big penises in pornography, and the only small penises aren't actually small yet are being made fun of by the actresses, these things have an effect on the psyche of many men, especially young men and teens who consume pornography, even those who are above the scientific average. In the 2000's alone the false misconceptions about penis size lead to the rise of Enzyte, a total snake oil product claiming to offer "male enhancement" which was advertised heavily on tv and ended up the subject of lawsuits with the owner of the company ending up in jail. But even today we still have many men who have a perfectly adequate size terrified that they are too small, buying various other male enhancement products and even going to plastic surgeons to get a lengthening surgery or inflatable girth implants. We need to end those misconceptions about size that has lead our society to this point. 

I don't know, maybe you're right, can't tell.

But now I wonder if you're below average

Above average, but certainly not huge. When I was a teen I obsessed over my size quite alot, like many teens do. Even though I started puberty young, at like 10, alot of my penis size growth didn't happen until my late teens, I was still growing some down there even at 19 and 20, and because of that late growth, and the viewing of internet porn as a teen, I got extremely worried about my size for quite some time and it really hurt my self esteem growing up. Even as an adult it has caused some self-esteem issues, because even though I'm above average I am tall and broad and it makes me look smaller down there than I often wish I was.

What do you conisder as average then ?

The average as found by over a dozen scientific/medical studies on penis size all across the world, which is around 5.3 inches long by 4.6 inches around. That average is slightly smaller than what Lifestyles condoms got in a study they did with Spring Breakers in Cancun one year, which was 5.8 x 4.9, though that study was reportedly conducted by young female nurses, so smaller guys might have been discouraged from showing up out of embarrassment, which would explain why they got a somewhat higher number than the medical studies.

But I am also larger than the often perceived average of 6 inches.
