I'm a girl obsessed with grabbing/touching/feeling/smac… and looking at boys butts!?

I mean, my father is an ***-man. He likes girls with big butts, but he has male children and they don't seem to be as obsessed with butts as he is. It's like, despite the fact that I'm a girl, his butt-obsession was passed to me [as well as his intelligence, knack for poetry and singing but that's a whole other story!]. This isn't a joke and I'm not trying to be funny. I just really like boys butts [although I don't think I'll EVER put my mouth anywhere near one] but it's like, it's so fascinating because it's the only part of the body that is just all meat, and softness :-). Okay, you know how when some men look at a girl's but and they're all like 'DAMNNNNNN!", or they have this look in their eyes that just says "That's a nice *** ;-)" its the same for me, even though reading that sentence makes me realize how funny this sounds :-). I think I really love butts but I want to know why? And do other girls share this trait? Most times, it's the men who are butt-obsessed, and I tried looking it up but all I saw were men asking this question. :-/ I'm just a little curious as to why I like butts so much?
