i know your asking ftm's n all , but i think i might know an answer
the simplest version of it would be this : any person , male or female , slightly and gradually changes in one direction over the years , less feminine , more masculine . for myself , since i was 10 years old i've always hated growing older for different reasons at each stage of my life, but before that (10 yo) i wanted to be older so i'm taken seriously
but after all everyone have different reasons , likes , and dislikes about age
