How do you straighten hair if your a boy? with dyspraxia!?

I'm 15, haven't got long hair, it's medium length, but i've got dyspraxia so coordination is all over the place. I've tried a few times in the mirror but can only straighten my fringe! I grab my fringe and straighten it but want all of it done, I have no idea where to start, how to grab it without burning myself.. ARRGHH
