If you still need help try this. Play a note then play the fret right after that. Ie. play 4th string 9th fret then play the 10th fret. Then play the 9th fret again then bend the string upward untill it sounds like the 10th fret. Go back and forth untill you get it right, thats a 1/2 bend. Do the same with the 9th and 11th fret and you get a full bend.
