I've had a bent pin on my first DSLR - a D70. My wife inserted a CF card backwards. There is enough resistance that you will be careful and it won't happen again. It's unlikely you bent it - but all it takes is a little mistake and some pressure by anyone handling the camera. Once a pin is bent even a little bit, there is no good way to fix it yourself.

The good news is the repair is pretty easy. Nikon or Nikon Authorized Service can handle it. You can call the nearest Nikon Authorized Service and get an estimate. It's probably around $300 or so for the repair - not cheap but not terrible either.
