I believe your comment is nonsense unless you care to elaborate and enlighten me. During a ride one is expected to sit with their torso tilted to varying degrees, from more upright to more aero, so one's posture shouldn't have an effect on whether their junk goes numb. If you are refering to whether one sits too far forward or too far back, then yes that could have an ill effect, however that has nothing to do with one's posture, that has to do with saddle for/aft position.
Just because "one is expected to sit with their torso tilted to varying degrees" doesn't mean you won't go numb. The biomechanics of cycling is not a perfect relationship. Far from it : ). Rocking on the saddle will cause numbess. Focus on making sure the pressure is on your sit bones. Actually, i'd recommend checking out the segment on velonews.com under velotv on fitting the spanish rider. There are 3 sections - in one of them the doctor talks about why the rider is going numb.
posture matters! it affects the pressure on the saddle
