Why do girls have to find me in particular attractive just to be "nice" ?

I've never been able to get along with either gender but mainly the opposite sex

From my experiences they tend to act very snobbish towards me from the get go & the ones that are "nice" to me are only because they somewhat find my slightly attractive

With everyone else these girls don't care what they look like

Wth me, they have to find me attractive just to be "friendly"

Any idea why this is?
