It refers to these "people of different sexes", which is what people usually call "transsexuals". However, the word "transitional" cannot correspond to the English word "transitional" because of its discrimination and inaccuracy.
TS are mostly male, and the ratio of male to female is about 3: 1. Psychologically, they deny their gender, think that their gender is opposite to that of external genitalia, and demand to change their physiological gender characteristics.
Characteristics of TS:
1, I'm sure I'm the opposite sex at heart.
2, claiming to be the opposite sex, but physical development is not the opposite sex.
3. Medicine is needed to change the body into the gender it recognizes.
4. I hope that people around me will accept themselves according to the gender they have experienced.
