This is the kind of thing you see on Tumblr.
Look, physically, there are two genders, male and female.
Neurologically, there are three, Male, female and transgendered.
That is biology. And besides, the MEDIA IS RIGHT, the definition is
denoting or relating to a person whose self-identity does not conform unambiguously to conventional notions of male or female gender.
,thee are two sexes: male and female. The word sex in our society is synonymous with gender, but many people consider them to be separate. Gender is defined as "is the range of characteristics pertaining to, and differentiating between, masculinity and femininity", so man or woman, basically. Masculinity and femininity are social constructs, and therefore so is gender. Usually, male = man and female = woman.
Physically, most people are male or female, but there are cases where people have some sort of mixture between male and female genitals, or their genitals don't "match" their chromosomes.
Transgender isn't a separate gender or neurological state, it just means that a person identifies as a gender different to the one they were assumed to have at birth.
You can change your legal sex (i.e. the sex stated on you passport),which I suppose is where the term "transsexual" came from, but not your genetic sex. Most transgender people change their legal sex.
