Did you buy this from a local dealer new? If so did they set you on it and adjust the saddle height and position? The tilt and height of your saddle might also be somewhat a factor. Since any reasonable LBS will want you to have a good experience with what they sold you, they will usually go fairly far with accommodating any issues you are having with your bike whether mechanical or fit. It's possible you might need a larger frame, or a frame for the opposite sex. Male and female frames can have differing geometries and tube lengths. They are made for the dimensions of what the company expects the median bike buyer will be for each sex. If you are not that median person, then the frame for the other sex might be better for you in the same size.
I personally see no reason for manufacturers to continue sexing bikes. I'd rather just see frames that spec the reach as well as the seat tube length.
