Sorry, dear, but it might also have been operator error. That happens to the best of us. If your shorts were too loose they might have come down farther, but cyclists have to learn how to hoist themselves up onto the saddle without spearing their saddles.

That's why WTB developed dropped nose saddles for MTBing and why mtb'rs like thin chamois or at least the v-cut at the back of the chamois - to avoid the dread short suck.

I know, still embarrassing . . .
