I am not going to try to have a surgery to make it happen.
There is nobody with no gender, there are rarities with natural double gender features, but strictly speaking, nature assigns a gender during early pregnancy.
All the ideas about gender changes occur to people later on and based on personal feelings/factors. The mind is something that develops by education and experience, not genetic urges as far I am aware.
If schools and parents would educate kids saying theres no such thing like gender and you get to choose and society lets the promoters of such go rampant, I imagine this would not lead to a net positive outcome.
