It means that he probably likes you. If the feelings are mutual, lean your head on his shoulder. If not... well, don't.
Thats generally a couple thing so it probably means he likes you.
Clearly the guy likes you and is willing to be serious instead of playing games with your head.
The guy is attracted towards the girl, but is not yet confident that she will like his kissing her.
I think it depends on the girl. Personally, I wouldn't do it. Only on my boyfriend's or extremely close friend's shoulder but otherwise no. But again, it depends on the girl.
If you are a girl, and a guy tells you that you intimidate him, it means he things you are too good for him and out of his league.
When a guy tells you he feels a pit in his chest, he means that he has a chest pain.
If a guy tells his friends that his girlfriend is quality, he means that she is a great girlfriend.
This could mean he likes you, BUT if you see that he does to every girl that is around this just could be a form of flirting.
She does not like him
Ejaculation
When a guy tells you he found the key to your heart it means he wants to be with you forever; he is the one for you
It could mean he's flirting with you. This guy always tapped me on the shoulder and then pretended he didn't do it and later on, I found out he had a crush on me. If he doesn't like you, sometimes boys do that for attention.
