My SNES is acting somewhat strange and I need to know what to do.

If I put a cartridge in there normally (straight down) I cannot get the game to work. I start to put it in at a slight angle, and then even it out, it does work. To better explain it, I put one end of the cart's contacts into the connectors before the other end. Is this normal behavior for a SNES console? Or perhaps it is my games? Also, will inserting the carts this way have any negative affect on them (I don't care so much about the console, for I can replace it easily)?

Thank you for the help, I really appreciate it!

Here are some pictures of what I am talking about:

This brings about GAME TIME!!!!
