I mean, some have both. I've heard of cases where AGP actually led to gender dysphoria (as opposed to just plain AGP).

To answer your question-- I think the ones who indicate distress at their sex characteristics may actually have gender dysphoria, or at least it sounds like it. The men on r/actuallesbians often make posts about their dicks, and invariably, in the comments section there will be at least one or two somewhat-upvoted comments by transwomen that say, "I'm uncomfortable with the fact that I have a dick, can we not talk about dicks all the time?" If any of them have gender dysphoria, it's most likely to be these people.
