I'm a 16 year old girl and I have tube's in my ear's! I just got mine replaced after 10 year's on August 14th 2009! Anyway if you have tube's and you get water in your ear's it would cause and infection! And I'm not sure but it might damage them! My ear doctor said I have to wear ear plug's when I shower or swim! And I do wear ear plug's! There is nothing wrong with that! :-) I hope I helped! Love, Christina
