it will make a difference, there is a spindle through your bottom bracket

push forwards with the right pedal and the frame flexes in one direction, push on the left and it will flex in the other direction

i think you ought to spend some time on sheldon brown and learn some bicycle terminology, it might make us helping you a lot easier if you used the same language as us
