I am not deaf but i am trying to learn sign language, i would appreciate a deaf pen pal.?

I really badly want to learn sign and i know that having a pen pal wont help learn it but i really just want to know more about being deaf and things that i would need to know to learn sign language. I am 15 by the way .

In American Sign Language, does it matter which hand you use to sign?

I am right handed but I found I’ve been using my left hand for signing the alphabet. I was just wondering if there’s a certain hand you suppose to use for certain words or phrases. This is my first time learning sign language so I don’t know much. Any other tips would be nice. .
