I have waited all my adult life to ask this question but never had contact with a big enough group of women! Mumsnet has come to my aid!
If anyone (including me) or anything touches the centre of the small of my back, just about where the bum-crack starts, I instantly feel that feeling you have when urgently you need to pee.
Even if I have just had a pee and thought everything was emptied out, let's say just before I get in the shower, if the flannel or loofah or my hand touches that spot, I instantly feel that "need-to-pee" feeling and if I let it, a bit of pee will always come out.
It's caused a bit of annoyance during sex over the years as sometimes that area might receive a caress or some pressure put on it. I then always have to stop and pee.
I've asked a few random friends if this happens to them and they said it did not.
At last I have the chance to ask a bigger group and find out whether or not I am completely unique in this!

IABU = no, you don't get that feeling
IANBU = yes, that also happens to you
