This question already has an answer here:
We can't deny that in this world, the human can be classified as male, female or unisex.
I design a form for registration. Does it really make senses to put all gender or just male or female only?
Let say, my form:
Choose your gender: 1-Male | 2-Female | 3-Unisex
Note: Does people really admit that the person was unisex?(Or become shame and preferred not to choose it?)
