The Internet says that men without throat knots have no manly taste. My throat knot is not very obvious, and I am a little worried...

Don't worry, not every boy will have a pronounced throat knot, and the throat knot has little to do with "manliness".
The laryngeal knot is actually a protrusion formed on the surface of the neck by the "anterior contiguous angle of thyroid cartilage". [1]

Before puberty, the thyroid cartilage morphology of boys and girls is not much different, they are more rounded, small, and less obvious from the surface of the body.
After entering puberty, due to the difference in hormone secretion between men and women, the development of thyroid cartilage begins to appear different, and most boys' anterior cartilage is sharper and more forward than that of girls, so the "laryngeal knot" is more obvious.
However, the sensitivity of thyroid cartilage to hormones during development is very large, and studies have shown that 40.5% of men and women have the same degree of anterior angle of anterior cartilage of thyroid cartilage alone, so it is unreliable to judge sex according to the angle of anterior contiguous angle of thyroid cartilage. [2]
However, the reason why some boys' throat knots are not obvious is more heart-wrenching -

In addition, genetic, endocrine, disease and other factors can have an impact on the size of the laryngeal knot.
In recent years, most scholars have no longer used the laryngeal junction as a reference index for male sexual characteristics in the research and analysis of sexual characteristics and secondary sexual characteristics [3-5], which is also a major progress in medicine.
