Is it normal that i cant say ''ch - ''

You're cute :)

So shocolate and shoo shoo trains?

it's not normal in the context of it being the way most people pronounce it, but you're definitely not alone. you just have some sort of speech impediment, possibly a lisp, which is nothing to be embarrassed about or ashamed of. if you want to get rid of it, you could always try speech therapy, but something like this may be caused by your jaw structure/placement of your teeth/motor control of tongue/etc., meaning you would have to somehow eliminate that in order to get the full effect. it's your own choice, of course, but I say embrace it! however you communicate is perfectly fine. :)

You should see a speech therapist to see if she/he can help you with your lisp.

Lisp

Hey, my mom is Filipino and says thr- as tr-. It's just the accent. You usually get one from hearing other people.

Speech therapy ...

It's called a lisp. It happens randomly if you strain your jaw for a long period of time or you get something in the way of your tongue. If you were born with it, it ain't goin' nowhere. Sorry.
