So I wanted to plug in my earphone jack into my Mac but I was not seeing so I accidentally and gently without that much force I put in my earphone jack into my Mac left usb port but it did not touch the pins. So should I worry that I have damaged my Mac?

Either your USB thumb drive is broken, or the specific USB port on your MBP is.
The easiest way to test is for you to plug another USB device to the same USB port, then
- Locate the Apple logo on the top left corner of your display, and click on "About This Mac"
- A window will appear. Click on the "More Info…" button
- If you're running OS X 10.6 Snow Leopard, skip to the next step. If you're running OS X 10.7 Lion, another window will appear on which you'll have to locate and click on the "System Report" button.
- A new window will appear, on the left column, locate "USB" which is listed alphabetically under "Hardware". The details of the USB device you connected to that USB port should be displayed. If it is, then your USB port is working normally, which means your USB thumb drive is the problem.
It sounds like you don't have your sound input configured correctly. Have you tried going into System Preference > Sound and changing the Output device?
Another (easier) option is to Option ⌥ -click the sound menulet in the menubar, which will bring up an Input/Output device selection menu (10.6 and later).

I wouldn't worry too much, the only two pins on a USB port that might have an ill effect if you short them together are the ground and power pins but they're located at either end of the connector so it's unlikely that would have happened with an earphone jack.
Additionally USB ports have over-current protection which is why from time to time you might see a message similar to "USB device was drawing too much power - USB devices have been disabled". In that case a reboot should re-enable the port. So unless you've physically damaged the connector, which it doesn't sound like you have, I don't see you'll have a problem.
Just to add a reference regarding shorting of pins from a publicly available standard, the Universal Serial Bus Revision 2.0 specification, sections 7.1.1 and 7.2.1.2.1:
Short Circuit Withstand
