Both you and the parent commenter are correct; A saddle that matches your personal anatomy will make a tremendous difference for all riding conditions, and the amount of times you vary your position on the bike will alleviate discomfort by allowing blood to flow naturally as your weight shifts. More intense riding conditions necessitate moving around on the saddle more often.

Additionally, if you simply ride your bike more often your groin and siting bones will feel more comfortable by acclimating to the pressure and movement. It's helpful to wear appropriate clothing in the areas that contact the saddle as well, such as a chamois liner, to reduce friction and add an appropriate amount of cushion.
