IPhone cable got wet please help (got shocked, scared to use)?

I bought a charger from Target 2 weeks ago so it's not from an Apple Store. Today I grabbed My charger from my room and carried a cup of water in the same hand, a couple drops descended onto the part plugged into the port and another drop onto the part that plugs into the phone.
I took Off the port and dried it with a napkin as well as the plug in parts and plugged it into the wall. As soon as I plugged In my phone my home button started to shock me (like when you touch a metal railing or car door) each time I touched it. I unplugged My phone and the port from the wall and let it rest.
A couple hours later I asked My friend to try it for me and see if she would get shocked by my phone being plugged in and she didn't! I didn't Either and continued to charge my phone.
I'm Scared thought to leave it plugged in at night or use it for a long time in case it starts a fire or I get shocked and die or something.

Should I just Get a new charger or continue using it if there's no problems? If you were in my situation what would you do?

Don't worry! You did it well by dried all the water out before using again.
To be sure both are dried well, put both in front of a table fan in high speed for at least one day, charge port and plug face to the wind, that help to take away the water more quickly.
Then both are safe to be used again.

Throw away
