Really depends on the babe in question. My girlfriend is very petite...at 5'2" and 105 pounds...tasty lil monkey too
But, she's over 40...definitely not a teen...though those perky lil tits say otherwise
I do have a petite category, so it's kind of a non issue at my list. I do still get petite submissions to my teen category...and like Surn move them as I deem appropriate.
