Yanks, for you. Listen up.
The flirting thing it was I dont completely understnad. How can you not know if a girl is flirting with you? By definition, it is obvious.
The problem might lie in whether or not you can truly believe that this girl might actually LIKE you, which is a self esteem issue.
If a girl says something sexual to you, suggesting that she is inquiring about your interests, penis size, or that she might want to find out or do something herself, that is generalyl flirting. There is a chance, however, that she might be doing this in a mockery manner. Maybe she IS
making fun of you.
The thing is to show confidence, almsot like you dont care. Not by saying that you dont care or ignoring people, but by doing your schoolwork, and doing whatever you have to do like those other thigns dont matter.
Lets look at the following idalogue. This is a girl trying to flirt with a boy, and a boy responding exactly how he should:
Girl : What's your shoe size?
Girl: Is it true what they say about guys with big feet?
Boy: (in a very calm voice with calm facial expression) There's only one way to find out.
Girl: Well let me see it
Boy: Ummm, you're going to have to work a little harder to get it.
Girl: Like how?
Boy: I dont know, when are you free?
The whole thing here is that the guy woudl be talking about this almost like he couldn't care either way, with a calm look in his face, MAYBE no more than a slight smirk and a calm voice.
By flirting BACK, you can then find out how genuine she is, if at all. That's hwo you will see if she likes you, is jsut playfully flirting with no intention, or making fun of you.
You act calm to shwo that you couldn't care anyway. So if it turns out that she wasn't serious, then your body language and mannerism tells her "Oh well, no sweat off my back."
Confidence is key, and remember that you're young and that if she doesnt want it, some other girl will down the line.
