I am 21 and i still wont go underwater without plugging my nose and closing my eyes. I hate water getting all up in my nose and the chlorine burning the things behind my eyelids in which I use to see. Nose plugs are for pussies, and all the haters that make fun of me for not learning can suck it! oh. p.s. I used to pretend i was the little mermaid in the pool.
Try exhaling slowly.
Also with rising water levels you better get used to it, and as for the mermaid? well i hope your not a dude (if so get help) lol
i'm a male, 12 years old and i still use swimming googles that covers the nose if i REALLY is gonna be underwater.
Googles is your friend ^^
