What are the common sexual characteristics of the body? What factors can affect sexual development

I firmly believe that some people find it difficult to accurately respond to male sexual work abilities. Some people even believe that lying in bed can achieve orgasm, indicating that they have strong sexual abilities. But what exactly does sexual function mean?

The male's throat, chest hair, female's breast, body fat, etc. are all called the Secondary sex characteristic, which refers to the difference between the sexes outside the sexual organs. They are the main manifestation of physiological differences between males and females, but cannot be matched with sexual function.

The second personality trait is mainly caused by differences in estrogen metabolism between male and female sex hormones (male testicles and female ovaries). Testosterone is a more critical and abundant estrogen in male blood. During the in vitro embryo stage, testosterone determines the division of the reproductive organs; During adolescence, testosterone further develops individuals into males and plays a crucial metabolic role in their daily lives. For women, estrogen can lead to individual differences.

Although estrogen and androgens have critical effects on the growth and development of sexual characteristics, their effects on the human organs are different. Taking chest hair as an example, the sensitivity of hair follicles to androgens determines the growth and development of hair. Some people's hair follicles are very sensitive, and even with low levels of androgen, male pubic hair under armpits and toes can grow and develop. Some people's chest hair follicles are not sensitive to androgens, so they have less or even no chest hair.
