Please use "want to" ... NOT wanna. "wanna' is how we write the sound of a native English speaker saying "want to" very quickly - it's only a sound, not a verb.
The explanation of when to use "being" is not a simple answer.
You can find many good explanations here:
2) Being + past participle Being can be followed by a past participle. This structure is used in the passive forms of present and past continuous tenses.
Mother is cooking dinner. (Active) Dinner is being cooked by mother. (Passive)
3) Being in participle clauses
Instead of a because /as / since clause, we sometimes use an adverbial participle clause with being. This structure is mainly used in a formal or literary style.
Being late, he couldn’t watch the show. (= Because he is late, he couldn’t watch the show.)
The word "being" is the present participle form of the verb "be." Usually, "being" is used after a form of "be" (is, am, are, was were).
He is being stubborn. Who is being stubborn? I was being helpful.
