Is this article coming from some alternate reality where people clean their ears for some dangerous guilty pleasure, and ear wax does not need to be cleaned away just as any other bodily secretion?
It's also a common anecdote that having your ear syringed by a professional is one of the most pleasurable non-sexual feelings. So yes, it's a thing. It's definitely a key part of the reason I [mis]use q-tips. I'm surprised by your comment that you had no idea it was seen as pleasurable!
There's a list of circumstances in which to remove ear wax here. And note that an article like this is written because doctors know people will try to remove wax when they don't need to, or via dangerous methods.
I expect to return to that page in another ten years and read, "Putting ice picks in your ears can result in bleeding. Christ, what is wrong with you people?"
Since then, I must confess I am addicted. I tried to wean myself from Q-tips use, but I can't. The little buggers cause something I like to call an eargasm, it just feels so good. They also cause more irritation just to make sure you keep using them - they are worse than cocaine.
Only watched a bit of one video[1], and I'm going to avoid watching any more. Can confirm that the sensation is surprisingly haptic, and it is viscerally uncomfortable for me. I'm feeling disgust and revulsion even as I'm typing this.
