Not having enough male companions is the curse of the Time Lords ;)
but seriously there have been male companions, but not nearly as many as the female. I alway like the male heroes. It’s a different dynamic.
Ian Chesterton, Steven Taylor, Ben Jackson, Jamie McCrimmon, Brigadier Lethbridge-Stewart, Harry Sullivan, Adric, Vislor Turlough, Jack Harkness, Mickey Smith, Wilfred Mott, Rory William, Craig Owens…
…but, yes, more male companions would be good!
