I am 22 years old. i take sexual pleasure in displaying my genitals. is there any cure for this?

Treatable: This condition has been successfully treated. Speak to a mental health professional.

So what: So what if you masturbate? It is neither physically nor mentally harmful. Therefore, there is nothing to cure. Go at it. As long as you have healthy relationships with others and your school/work is not affected, it is of no harm and of no concern to anyone including pastors/priests or family.
