Left Handed

Hello Sir .

I have a little question . for students how are naturally left hand , should we hold the harmonica with our left hand and make Wa Wa effect and other effects by our right hand , coz usually our strong hand and more effective is our left hand , and for myself i find little bit problems to vibrate my right hand coz its the weak hand not the strong effective hand ,

so can we use our right hand to play the harmonica , or should we stick to the holding harmonica with left hand and practice our right hand to be more effective , please tell us what is the best , and if holding harmonica with left hand will effect playing the harmonica and will effect learning techniques in future ?

thanks for your time reading this  . looking for your answer
