wow, the things you learn here..Yes, as a women, I too had issues with emptying my bladder.
At first it felt forced,
then pressure around it, now I"m ok there.
This is what a Doctor, told a friend of mine, He told him to take a low stool or seat and place it in front of the toilet (face the toilet sitting on stool) lift your legs up(just like you would be sitting on a toilet having a BM) It worked for my friend,Oh yes and aim, sorry I'm so graphic.. Please try it.
I hope it works for you.
