Speaking very "generally" about dogs.
Male dogs are often bolder and more aggressive than females, although in some breeds it is the female who is "sharper" and more aggressive while the males might be described as "goofy" or "klutzy" or "big softies."
Female dogs are often less pushy and "in your face" than male dogs are. Yes, females are affectionate, definitely, but often it's on their own terms. They may request lots of petting, then assert their independence by walking away when they've had enough.
