hard to get into reverse

i was wondering if this is all stangs or just mine. when i try to put it in reverse(5 speed tranny), it seems really hard, and i have to force it into reverse pretty hard. sometime this even happens in first gear...does this happen to anyone else? it must be bad to force it into gear, right?
 
I have had this from time to time. This seems to happen on most 5-speeds and not just stangs. I have noticed this on past cars (my Integra, my talon) and current cars (my Stang and my truck).
My fix that seems to work each time is not to force it into the gear that won't go, I doubt it's good for the tranny. If it won't go into 1st I put it into one of the middle gears (like second for example if you are trying to go to 1st) for just a moment. This seems to unlock 1st then. For reverse I just slip it fully into another gear that is close by like 5th. Do this for just a moment also and then slide it into Reverse.

I think it just depends on where you stop the tranny. It seems like it gets stuck between gears or something and it just takes some other gear movement to get it unstuck. :shrug:
