If the saddle height is correct, you really need to ride with the back half of the saddle dead level. If the support platform is level, your weight on your pelvis - your sitbones. If the saddle is tilted forward, your pelvis will tilt forward, putting your weight on the soft bits. That will result in pain, numbness, or a bit of both.
If you have crotch pain on a level saddle, it generally means the padding is too soft, and your sitbones are sinking into the padding, putting pressure on your crotch. Try a medium width Specialized Body Geometry saddle with the firmest padding you can find. A firm saddle with a cut-out in the center puts all of your weight on your sitbones.
