There seem to be at least two forms of dysphoria, when it comes to trans shit: social and body.
Social dysphoria is the dysphoria that comes from how others treat you. It's when I get called 'ma'am' by the waiter, or by everyone on the phone, or how I can not fit into any article of clothing in the shop that I want.
My social dysphoria is pretty minor. It's annoying, but it very rarely spurs me into rage. Sexism exacerbates social dysphoria, but it doesn't create it. People can be perfectly kind and polite and still cause social dysphoria--think of all those well-intentioned people who tell me what a pretty girl I am.
Some people want to pass or transition to ease social dysphoria. In my case, I do not; I have enough folks around me who treat me properly that I don't mind. Also, it's never been my huge issue.
My issue tends to be more body dysphoria. It's quite basic: parts or traits of my body are wrong.
