Seriously? Drop the double standard.

"Oh he's so hot."
"Yeah, I'd never date a fat guy."
"Mmmmhmmm I need a six pack."

Ever hear this conversation? Ever hear it out of a group of rather obese girls?

How about this one:

"I can't date fat chicks."
"They can't be too skinny though."
"Dude, as long as there's boobs I don't care."

I bet you've heard this conversation. How about out of a group of either underweight or overweight guys?

Oh yeah. I've heard it.
And then I hear them complain. Why don't I have a boyfriend? Why don't I have a girlfriend? I'm a nice person, I'm smart, I'm funny- Why can't people just look past my appearance and see the real me?

Uh HELLO? Seriously? Drop the double-standard! You want to have a great relationship? Try this.
Instead of automatically tuning out the people around you that doesn't fit your "perfect body type" - try to locate people based on their personality. Just like what you'd want someone to look at in you.
You want to be noticed for your kindness? Look for a girl with a sense of humor. You want to be noticed for your intelligence? Look for the polite guy holding the door. Don't just zone out on anyone who isn't perfectly athletic, or blonde, or not blonde, or too short, too tall, not busty enough, or too plain.
And you know what? Chances are, if you're looking for someone like that, you won't end up going for the "hot jock" or "babe" who turns out to be a total douche/bitch.
