Sorry if this has been discussed before, but I was wondering what happens if someone changes their legally recognised sex, then changes their mind having not had any surgery / hormones etc. Could people change sexual identity repeatedly? Or is it one chance only? - in which case anyone considering it had better be sure. (This is having read some of the Meanwhile in Ireland thread)
And also, weirdly I was thinking about Sue Pascoe and descendants of the man that was the person before the legally recognised as female Ms Pascoe. What happens to the original birth certificate? If someone is researching their family tree in years to come, do they just draw a blank at that point in their history?
