I need some answers about...?

It's totally normal chances are you just haven't hit puberty yet. You said you don't have facial hair so that is probably what's going on. You really just have to be patient. About the smell, you probably just aren't cleaning the area well enough. Especially if you aren't circised you need to make sure to pull the foreskin back and clean the area well especially during the summer when its hot and you are sweating more.
