the difference between drawing men and women is that you give more toned definition to a guy's muscles, or else you'll end up with tons of girls that look like pretty men, and make the guy's waist and torso align, instead of the torso being thinner than the waist, wider posture is also pretty masculine, hair and facial features can vary. (and give guys flat chins, girls pointy chins, there's also an eye skull indent that looks pretty masculine but I don't know how to explain it)
