I’ve worn HAs since 2nd grade, and back then you dont want to be seen as “different”, so yeah, back then it was embarrassing. Since growing up, it’s not an issue, as people earlier in this thread said, it’s like wearing glasses.
I actually use that analogy when asked by a child what those things are (watch the parents cringe when their kids ask that question 
)
BTW, once you explain what they are, they don’t give it a second thought.
