Why dou you think you need dysphoria to be trans? And other questions...

Hi, im a trans guy with dysphoria, i just wanna ask, why do you think you need dysphoria to be trans? Why do you think a he/him lesbian is just a man? (And what you think of afab hesbians, they're just trans man in denial or what?) How and why are pronouns gendered? Please, don't be aggressive, i just wanna read your arguments, sorry if these questions may be aggressive and sorry if someone dont understand what i trying to said, im not an english speaker.
