I dropped my iPhone 6s in the toilet?

I had to pee really bad but I was fussing at my brother for peeing on the toilet seat and not wiping or flushing. My phone was in my pocket and when I pulled my pants down it fell in the pee water (gross!). I screamed and took it out immediately and tossed it on the carpet in my room. Mind you I still had to pee so after I finished using the bathroom I picked it up and took off the case (it's a clear back case). This was probably my first mistake, not taking the case off right away. Then I ran downstairs and got a paper towel to dry it off and I also tried sucking out the water from the ear bud ports and the other little holes but I forgot my brother peed in the toilet and didn't flush also I got pee water all in my mouth (gross again!). My mum put it in rice and we left it there over night. The next morning I went to see if it was working (because after I dried it, I was using it to search what to do then it started acting weird and I couldn't touch anything) but I guess it turned off overnight and it wouldn't come back on. My mum and I tried to charge it but nothing popped up so she took it to work with her to ask one of her coworkers what to do. She told her we did all the wrong things, that we had to turn it off right away and not touch it. This happened Monday night, it still won't turn on. What do I do?

Way too many unnecessary details.

You dropped your phone in water and now it no longer works. Nuff said.

What do you do? You replace the phone. It's damaged internally and can't be repaired.
