Is it true that a guy will only be friends with a girl if he finds her attractive?

yes it is true but not just physiscally attractive. it's true of girls and guy's in the end people only do things for themselves. They will only be friends with a girl if they find her atractive in some way. She is self confident, beautiful, she has some quality he wants or admires, he wants something physical from her like money, she's funny.

I actually think it's the opposite. I would never want to be friends with a girl I find attractive. I don't want to have sex with my friends. The female friends I have I am not physcially attracted to.

In my opinion, guys that befriend girls they are attracted to only do that because they aren't attractive enough or don't have the confidence to ask the girl out. So they think by waiting in the wings as her friend she will miracously see how good of a guy he is and ask him out herself.

When ever a girl is asked if her and a guy she's with are dating and she wants to clear the air what does she say?

"Oh, no! We're just friends!"

Why would any guy want a girl he's attracted to, to say that?

it depends on the guy. some guys become friends with a girl the find attractive because they're shy & want to get to know her better & some guys become friends with a girl that they find attractive because the just want sex or more than just a freindship from the girl & they figure that this way the can earn the girls trust making it easier for them to get what they want. good luck & I hoped I helped.
