Are submissive gay total bottoms that have no desire to use their dick for fucking or even getting it sucked...

...Are they most likely to be some kind of trans woman whose dysphoria never manifested?

Gay guys have tops, vers/tops, vers, vers/bottoms and bottoms. Psychologically are all 5 of these types sub categories of gay guys or are total tops gay for different reasons than total bottoms are gay?

tl;dr: Two homosexuals, one is a bottom the other is a top, are they like... different kind of gays?
