Yes. Things can get squashed if you squeeze your thighstightly together, as you need to do occasionally in ballet.
> 2- to keep the penis pointing up instead of out
Almost. The idea is actually to keep it from pointing *down*--that is, to keep it from obstructing the line from the feet clearup to the pelvis. Ballet is an art that favors long lines, andthe legs should seem to go on up forever. Having nothing showingat the level of the perineum helps create this illusion.
Hope that helps.
