Is my body complex oddly distributed?

I'm 19 years old and work out. I was looking at myself the other day in my bedroom mirror when I saw that my body was oddly proportioned comparing it to the normal male body.
I say this because:
1. I don't have broad shoulders making my upper body looks small
2. My lower body is big than my upper body compared to my slim body

I don't workout my lower body but it's been bigger than my upper body ever since puberty. Don't go thinking I have a huge bodybuilding lower body it's just big compared to the slim body I have.
I say that I have a big lower body because I have; strong calves, wide thighs and a prominent butt.

Is my body complex oddly distributed?
Do women find men with prominent legs and butt attractive?
