Yes!! My voice is very deep for a girl, and I wish my voice was very light and cute to match my personality, but I wish I could change it!! I hate my singing voice too. I try to make it higher and everything :/
I used to. I have kind of a high pitched voice so I sound a little younger than I actually am. It doesn't help when you've been told occasionally that your voice is kind of annoying.
That being said, I stopped giving a hoot after a while.
Not really. I don't usually care except for those times when I say nice or sweet things or whenever I say I love you. It always comes out as flirty even if it isn't my intention.
