Search Results: no physical contact

When I get a crush on a guy, it doesn't necessarily mean I want to date him. That was the case in high school. I noticed if a guy is nice to me, has a funny sense of humor, is cute, and I feel comfortable talking to him, I start thinking I have a crush. I tend to idolize them and i think they can tell.

Let's take this guy for example: This guy sat next to me in one college course. He was the first cute guy to walk in the classroom and he sat right next to me. I was super happy. We started talking and i thought he was so cool. I would look at him--I dont know if he notice-then i would look at my lap and fiddle with my hands. I laughed at most things he said.
If a girl did all this what would you think?

I read that some girls flirt by laughing at a joke while gently pushing their crushes upper arm. I never touch my crushes. Can guys tell if a girl is flirting if there is no physical contact. Either it is obvious and they don't like me back as more than a friend or just a person. Or I think they can tell I like them, but I am wrong.

*Note
There is a huge lack of men in my life. I love my dad, and we have a good relationship, but there isn't much emotional support and he lives in another state. I have an older brother, who is 4 years older. We never got along growing up. And now he is at University out of state and rarely calls me. The strange thing is, even though we are not close at all, I admire him and think he is the coolest guy I have ever known. I wonder if that has anything to do with why I get crushes so easily on guys who have qualities similar to my brother, but are actually nice to me and enjoy talking to me.

Thanks.
