I wonder why you write well generally and then use the word wanna?
It's not a word in the English language and only serves to detract from your writing. It's slang for the words, want to, used in speech when people's pronunciation is lazy...writing it that way just makes your post seem like a child wrote it.
The way you write represents you as a person so you should think about writing as best you can.
