Oh yes - I'm one of those people. Sticking a q-tip in your ear feels soooo good. It's ticklishly, itch scratchingly good. It also feels better the longer you leave it - if I've not used one for a few weeks it's a genuine pleasure.
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!
