To be sure, gender and sexuality are entirely distinct. A man may feel extremely uncomfortable being required to wear a dress, and that has nothing to do with whether he is sexually attracted to other men, or women, or both, or neither.

Gender is about presentation in society, and there’s no reason to assume that children can’t understand it or know that the presentation they are being required to have do not match how they feel - like that man forced to wear a dress.
