Penis Science
1? Various Myths and Shapes of the Penis
The shape, size, and duration of intercourse are focal points for men, and discussing this topic often leads to feelings of inferiority or nervousness.
However, it doesn't actually have an absolute impact on sex.
Since ancient times, there have been various myths and sayings about the penis. For example: overuse will quickly lead to decline, not ejaculating during intercourse allows for longer duration, the more you train, the stronger it becomes, and without training, it weakens…etc.
Previously, some people even ranked men's penises in order of preference: 1. Black, 2. High angle, 3. Thick and large, 4. Purple, 5. Bare shaft, 6. With warts, 7. Curved, 8. Tenth dog, 9. Rotten, 10. Foreskin.
The meanings, in order, are: black color, high angle, thick glans, purple color, sheep's eye ring, beaded, curved left and right, infertility, impotence, inability to evert.
Generally speaking, the shape of the penis can be divided into six categories, as follows:
(1) Mushroom type. The glans protrudes like a mushroom; this is the shape of most Eastern men's penises, and it is quite pleasing to women.
(2) Test tube type. The glans is not as large as the mushroom type; the overall shape is slender, slightly inferior to the mushroom type.
(3) Baseball bat type. Like a baseball bat, it is a medium-thick type. The upper part of the penis is thicker than the glans, which may make women worry about it getting stuck.
(IV) Cucumber type. Similar to the baseball bat type, but thinner overall.
(V) Boat head type. The glans is upturned. Few people have this type. It is a top-tier penis and is highly valued by women.
(VI) Triangle type. The type that gets thinner towards the tip requires some skill to satisfy women.
2. Various bending and twisting
situations:
The penis is bent to the left or right. The proportion of these two types is 57%, which is more than the proportion of the straight ones. And a bent penis is more likely to make girls orgasm than a straight penis.
Left bend -- "Left" Zongtang: "Those who are right-handed, all of you, stand over here" -- 38%
Right bend -- "Right" Ren: "Those who are left-handed, please come to the right..." -- 19%
Straight -- Chiang "Zhong" Zheng: "The rest, just stand at attention and don't move." -- 43%
Twisted situations:
Twisting to the left -- the other person can orgasm as long as you insert "to the left" during
thrusting -- 24% Twisting to the right -- the other person can orgasm as long as you insert "to the right" during thrusting -- 23%
No twisting -- the other person can orgasm only by thrusting "to the left" -- 53%
3? Hardness and size testing standards
Generally speaking, the hardness of the penis of East Asian men is superior to that of European and American Caucasian men, but the size is longer in the European and American men.
Hardness Testing Standards:
────────────────────
Equivalent Hardness Hardness Index Order of Female Satisfaction
────────────────────
Damp Towel Wringed Out 100 3
Rubber 80 1
Raw Rubber 60 2
Fish Cake 40 4
Lip Cake 20 5
──────────────────────
Size Testing Standards:
According to survey data, the standard average length of the penis is 12 cm and the girth is 3.5 cm (diameter). Among East Asian men, approximately 80% have a penis length of 12-15 cm.
Recently, the University of California, San Francisco, also presented a scientific study. Measuring the size of sixty healthy men during erection, they found that the average length was 12.8 cm and the girth was 12.2 cm.
The study was led by Dr. Bo, a urologist at San Francisco General Hospital. S points out that the clinical measurements that give the impression that American men have large penises are actually incorrect, creating a misconception that leads men to line up for penis enlargement surgery. In fact, less than two percent of men are actually suitable for surgery. Moreover, even those below the standard size don't necessarily need to be enlarged. It's entirely a matter of sexual technique.
