Would movies like Commando and Rambo: First Blood Part II be trying to appeal to females more, since they have muscular shirtless guys in?
That's a negative, Ghost Rider.
Those films are very much aimed at teenage and young adult males. The shirtlessness there is not for female appeal, it's to provide a sort of ideal male image - "You could look like this if you were an action hero and spent 14 hours a day at the gym."
If you're looking for movies which did deliberately play up the shirtlessness of muscular men for at least a certain amount of appeal to young women (and teens), look no further than
300 (2006) or
Twilight (2008), and, increasingly, more recent superhero and action movies (Aquaman and... anything with Jason Statham).
