I don't think it means they want a naked picture of you unless your talking to a complete pervert. I think it simply means what they asked for just a picture of you. If it's someone that you are dating or something kind of like that they may just miss you and would like to see you anytime they want.
It is to remind you of him. He probably likes you
He probably likes her.
yes or the guy is just flirting with the girl
I think that means Picture for Picture
It means that since the guy moved on he asks the girl if she has moved on to to have now made her now let down easily.
to know whether she is younger than that guy or not...
To be his regular girlfriend.
it means you like him but if he asks you to then he likes you!
No, because what if the boy asks a guy and what if the girls asks a girl? So the answer is no, but it depends on how the person will look when asking the question.
He's trying to woo you....
it means that he loves her This means that he is interested in her.
A guy who asks that question is worried that you do not fully respect him. It is up to you whether you think he should be reassured or not.
guy asks girl end of
it means he wants to have sex
