Thanks for all the input, everyone. Since the cycle I rode in the Century was a rented bike that my fiance arranged for me (himself an endurance athlete with four ironman finished under his belt--i.e., not a slug or slacker, so he chose carefully) I have no idea what that saddle was.
Yesterday was my first day back on a bike after 2+ weeks; I rode a Lemond with a Terry butterfly saddle.
Since I do triathlon, I too have determined that it is best I stay off the saddle and run, swim and dance (which I also do) as my forms of exercise until the numbness completely abates. From what I've been able to research on the net, the point of trauma is the pudendal artery which controls blood flow to the urethra, clitoris and vagina. (A woman named Dr. Collins in the process of conducting a multi-year study specifically on women cyclists to address our health issues.) This atery is the female equivalent of the perineum artery, which is the one that causes male cyclists' genital problems. In both men and women, the artery in question is flattened after prolonged pressure is applied. It does appear that I have not caused permanent nerve damage but that the blood flow was constricted, is still constricted, and will simply take time to regain normal levels of blood flow while the artery regains its natural shape.
That's what I've learned so far. Big Fat Drag.
But at least I really don't think it's permanent.
Once healed, I will shop for the saddle that is right for my anatomy. In the meantime, I'm learning a lot.
