As a flight instructor with several young female students (Yeah! Some more women in soaring maybe!) I'd be a lot more interested in hearing any women pilots address this, because I think the problem for guys is simpler and better understood.

There are any number of devices on the market for female athletes, hikers etc etc

I don't know how hard it is to get a good seal.

I fly a Discus B, and my solution for it is really simple: I carry an empty plastic Snapple ice-tea bottle, with cap. There's room between the control stick and me, angles work OK.

This doesn't work for me in every glider -- in particular it sure doesn't work in a friend's DG-101 with the parallel stick mechanism that leaves no room to my crotch.

Whether this works is also heavily dependent on whether you're a "grow-er" or a "show-er". We grow-ers have a more difficult job, assuming we're not all that excited at the time.
