Just remember to NOT use the sealing cap WHILST diving...
Reading through the posts, i kind of think that 12hrs+ in the device _not_ underwater (AKA, driving, climbing, hiking, etc..) is a bit optimistic with regards to not need to do what lynne says and dry/restick at some point in time. I find that the thong underwear and boyshorts help dramatically for many women, as does the grab and pee technique. Its not the in water time that loosens it up (at least for me), its the hiking, sitting on it in the car sweating, etc... I've done 8-10hr in water days with no leaks... I've done a drive to the dive site on a 90 degree day and needed to peel, blot dry, and restick before the dive.
and just to be safe, i use a poise pad
How many women are using poise pads during their learning curve?
Even if it comes a bit loose, if you press it/grab and pee, you can still get 90-95% or more of the urine out the pee valve.
I know of one lady who uses no tape or adhesive, just thongs and tight boyshorts, she just grabs and pees when it's time... Not something I'd recommend, but I guess if you gotta pee and you are allergic to everything, you do what you can...
The reason we actually went to using the QD is so that we can click in and out easily... back in the day, when we had to tug and twist and press the barbed fitting into the she-p itself, before the QD and extension, connecting/disconnecting was indeed a concern for increasing potential for leaks...
