First of all, the word is SEX, not GENDER. If you are ever tempted to use the word GENDER, don't. The word is SEX! SEX! SEX! SEX! For example: "My sex is male." is correct.
"My gender is male." means nothing. Look it up.
What kind of sick neo-Puritan nonsense is this? Idiot left-fascists, get your blood-soaked paws off the English language. Hence I am choosing "male" under protest.
