I obsess over staring at hot women's butts
Where do you go to stare at women's butts?
I'd stare at their butts on the street.
You should try to be a little more discrete. It is not kind to obsess over women in a public place.
They are assholes for wearing something so revealing.
Starting at the butts of women is a pretty rude thing to do. While it may seem that they are dressing revealing, it does not give you the right to make them feel uncomfortable.
