How common are men in your world? There are 3 easy fixes you can do to the Who Are They Table to include men.
One is to add a column to the table & change the headings to 1 or 2, 3, 4 or 5 & 6. Make all of the rows in column 3 say men.
The second is to add a Chance roll to one of the column - 4 or 5 for instance, add a Chance that (1-2) will be men instead. So if you roll a 4 or 5, roll another d6 & if it is a 1 or 2 then you have met men instead of Ghouls, Ogre, or Orcs.
The third option is that men are so common in your world that you roll 1d6 and on a 1, 2 or 3 you've met men & 4, 5 or 6 consult the Who Are They table.
Those are the easiest fixes I can think of off the top of my head.
Amado mio, love me forever and let forever begin tonight.
