It depends on the boy character. Is he want sex from you then he will not feel shy to come to you without any surity. But if he has family values then he will make sure of everything. surity here means boy is mature and wants to give girl the time to think about the relationship.
He may seem nervous, look at you, smile, stare or even tease you it really depends on the boy himself - if he is outgoing or shy would depend on how he acts.
It probably means he likes you and is getting a bit self conscious . He is unsure in his mind what to do about it. He needs you to make it a bit easier for him by you showing some interest in him. If that is what you want.
Guys get shy too. Even if they are outgoing, they still get shy. Also, he may want you to just do something to make your relationship better. If he does and starts everything, you wont have a very strong relationship, so just try to do something. And remember, if you dont wanna make a move, tell him. If he really likes you he wont get to mad.
It means he REALLY likes you. Maybe even LOVE.
joke around with the topic until u find a point to be serious about it
No, he would like you if you spoke decent english. If he says to 'off', he means, leave him, until he calls for you.
Maybe he doesnt know how to start a conversation with someone he likes, maybe he is nervous around you.
Until Miley Cyrus publicly states that she still likes Nick Jonas, there is no way to know.
No, not really, it probably just means he likes oral sex and was lucky enough to find someone (namely, YOU) to give it to him. Has he called you? Asked you for a date? If he does and you agree to go out with him, don't do it again until you are sure he really likes you for you and not because he thinks you are easy. AND ALWAYS USE PROTECTION-EVEN WITH ORAL!!!!!!!!!!
I've heard that they really like it when you know a lot about a topic he likes, and he really likes it when you know even more about the topic than he does
they can get really really upset so don't even try to tell any1
There are ways to tell. Firstly, it depends if he's shy or outgoing. If he's shy...it's harder to notice. For shy guys: When (if) he stares at you, and you catch him staring, he'll probably look away really quickly. Also, he'll be really nervous around you, and maybe even shyer than he usually is. If he's outgoing: He might be shy around you as well. Same as a shy guy, he might be fine and outgoing around everyone else (including other girls), but when he's around you, he'll be nervous. His friends might know as well, so look out for that.
