Why is my iPhone 5 having trouble with the headphone plugin?

Last night I was listening to music, and everything was fine. Today I was trying to listen to music with my studio beats, and it wouldn't work so I replaced the batteries in my beats and it still wasn't working. I tried a different pare of headphones, and it still wasn't working. I have and iPhone 5, and when I plug headphones in, the music plays from the external speakers, and not through my headphones. I have been doing lots of research on it, and it might have water damage. Yes, I have dropped my phone in the water before, but my phone never touched water in between the time I listened to music last night and this morning. Right now, my phone, is soaking in rice. Hopefully that might help a little bit. What should I do? I can't take my phone into the store because i'm 14, and my parents will be upset when they find out. I love listening to music, and I don't know what to do if I can't get this fixed! Please leave me tips down below on what i should do or try. ( I won't be able to restore my phone because I don't want to go through all the trouble and/or take the chance of losing things ) Thank you for anyone that helps me!

Be more careful with the replacement.
