Why do i like petite girls so much?

i'm 6'1 175lbs 19yrs old male and whenever i see a petite girl like 5'5 below,I feel like I wanna carry her and toss her here and there.Get all rough but not too rough.Why?Am I weird because of this?I'm asking here on yahoo answers because I don't dare to ask this question in front of the ladies.The 20-30 of them might gang up and beat me with brooms,heavy files and mops.
