I think the point is rather that self-diagnosis is notoriously unreliable. That's not to diminish what you've experienced, but you'd hardly be the first to be told you "have some symptoms, but to qualify for a full diagnosis they'd have to be significantly worse".
It's died down a bit now, but there was a whole "undiagnosed mental disorder" craze on social media for a while, with loads of people claiming they had some kind of one-in-ten-million disorder. And of course in their videos they'd exhibit the symtoms but eventually they either were found out to be outright lying, or some had to be told by doctors that what they were doing didn't qualify as a mental disorder.
Again, not trying to minimize what you're experiencing of course (and I definitely don't think you're lying or anything like that). You seem very genuine in your answers and your experiences seem genuinely debilitating. But I don't think anyone here is qualified to actually determine whether your self-diagnosis is actually accurate.
Imagine, in a few months time an expert sits down with you and points out XYZ that would actually suggest you don't have this disorder (but perhaps something else) or it's not so severe to warrant a diagnosis, even if it's debilitating to you (e.g. "someone with hypersexuality wouldn't be able to not kiss someone hovering next to their face at all", or something). Everyone coming across this post won't be told about that, and people may either relate with your experience, and then possibly wrongly believe they have it too, or maybe someone who does genuinely have it may not relate to your experience and wrongly believe that they must be suffering from something else.
Your experience is still interesting (and real, not trying to undermine you here), and so is this AMA. I can also understand your gripes with the medical system. But for caution's sake, it'd be wise to not outright state you have hypersexuality (even if I believe you probably do), but rather are likely suffering from it, or that you're in the process of getting diagnosed for it. All still true statements, and they don't detract from what you're going through, but structured such that it won't by accident cause someone else to believe they have or haven't got it too just in case you end up being wrong about the diagnosis (which again doesn't detract from what you're suffering from, it just might need a different label for example).
