I have a table of users. Can I count how many males and how many females without multiple queries?

This is not PHP!
select sum(iif(sex='M',1,0)) as males, sum(iif(sex='F',1,0)) as 
from somefile
There is a cleaner and more easily-optimized way (when using indexes on
large tables, this will be significantly faster):
SELECT sex,  COUNT(userId) AS sexCount
FROM users
Then, you will get two rows back:
sex | sexCount
M | (number)
F | (number)
