@Moonbuggy Where did you get that 99.98% figure, that is not even remotely accurate.
Any figure backed up by science (peer-reviewed facts) generally. If we use the definition of intersex the current numbers are 1.7% according to scientists who are born with some form of intersexuality. Thus would not be defined medically as female or male strictly speaking.
I personally prefer to deter people from asking others about their genitalia unless they are sexually intimate with the person. As such I usually prefer not to answer that particular question.
Considering that medical science disagrees with the. number stated then it would appear he would make statements that are both willy AND nilly.
