The best way to lean a surfboard?

I got this problem. I know not to give up and stuff, but like whats the best way to lean when i do get up. It seems like when I do stand if i lean back at all the board flys forward and i get flung backward. Lean forward and I end up nearly doing a flip, nearly. Usually I end up going head first into the water or get smacked around by my board. Does anybody have like tips on body weight and positioning once you get up and stuff.
