Why are ugly boys more confident then pretty girls…?

Just something I noticed.

I have 2 sisters and 2 brothers, My brothers are very ugly (Sorry but I'm being honest) And my sisters are very pretty. My brothers are so confident and cocky, One of them always runs around no clothes even though hes pale skinned, has a big beer belly, body hair, and a small 3 inch uncircumcised ! and the other one walks around in hes pants all day. They love the way they look and are always looking in the mirror. Yet my 2 sisters are both very tanned skinned, have good bodies, very toned, Yet they don't even wear bikinis.

This is the same with all my guys friends, They are alll soo body confident and they don't even take care of them selves or how they look.

I think that's why so many girls are prude because they are not body confident like the boys are.

Any body else notice that boys are more confident than girls?
