not what i was hoping to hear....but not unexpected!
There's a bunch of nerves and blood vessels down there that your aren't supposed to sit on. Read up on the whole 'sit bones' thing. But you can also get interesting effects from your lower back without even realising it's coming from your lower back. My 'bits' go numb if I ride the trainer (dunno why, just doesn't work for me), or if I ride in an extreme aero position for too long - but everything comes back to life after a couple of minutes.
I've heard of someone who did the 'gong ride, got numb hands, kept going... still had numb spots a month later. Don't know if he got an answer, but the two possible causes there were carpal tunnel or pinching of the ulnar nerve in the elbow.
I ride, therefore I am.
