That doesn ' t make any sense . There are two types of genitalia that have ever existed for human beings , besides the fact of evolving from asexual single cell reproduction . So if there are literally only two types of genders because of the fact that there are only 2 genitalia types which actually interact successfully , then what is this ? I used to know people that called themselves demisexual . Pansexual . Go ahead . Just because your physical body is right doesn ' t mean your brain has to be . Amen . Edit lmao intersex , I ' m sure the ultimate creator up in the sky wanted there to be intersex and other genital forms , so why don ' t we just genetically engineer new sexual organs for those people who refuse to fit under Straight , Bi , or Gay ?
