yes it does. i've been pretty lucky most of the time, just bruised thighs, but its very possible.
Stupid question here, but would it be too mouch of a pussy move to wear a cup? Yes, its not very "ballsy", but in all seriousness, I would like to have children.
Also, a lot of urban crashes look nasty, partially becuase you're falling on metal/concrete stairs, but also because the rails are often held up by a few vertical bars. You can catch a ski or a pole and really get wrapped up in it that way. Any way to avoid that?
