YABU - it happens to me
YANBU - never experienced it
Just that really. The male equivalent is so well known and talked about (I think it was even covered in either biology or PSHE at school!). I never realised the same could happen to women so was pleasantly surprised the first time it happened to me. It's not a common thing for me, averaging about once every 2 years since I was in my early 20s. Often when I have a full bladder, usually accompanied by an appropriate dream but not always.
