MY gender is he/him/his. Plumbing fittings have genders. Electrical plugs (male) and sockets (female) have genders. Mechanical parts have genders.
If the system wants to know something biological, like whether I am male or female, the correct thing to ask would be my SEX. Can we please use correct terminology? "Sex" is not a dirty word.
A new user preference has been added, allowing the user to specify their gender.
