I have no experience with female boxers, but I've heard that they're much more independant than males. I've also heard that males are more clingy than females. In my case that's 100% true with Riley. He's almost always right behind me whenever I move around the house. It doesn't matter if I go into the kitchen, the bedroom, or the bathroom, if he's awake he'll get up to follow me. Sometimes he'll be nice and comfy in bed and he'll hear or see me leave the room, but he give me a couple of minutes to see if I come right back. If not, he'll get up to come find me. I wouldn't want it any other way though.
Mason is more independant than Riley, but he does follow me around a little bit. More times than not though he's off doing his own thing. He loves playing solo with his toys.
If your gut is telling you to get a boy, then by all means get a boy. You know you're going to cherish and love the new puppy whether it's a boy or a girl so why not try the "other side" to the breed!
