I was absolutly convinced as a pubescent teenager that I ahd been born a boy but that Mum had so wanted a girl that she had made someone cut off my male equipment. I felt that someone had done a very poor job and had left me disfigured (in fact I still have a somewhat poor body image!)
It wasn't until I was quite a lot older that I realised that labia are a totally normal part of a female and vary in size from one woman to another and have nothing to do with the clumsey removal of amle genitalia. Oops!
