It means that he probably likes you. If the feelings are mutual, lean your head on his shoulder. If not... well, don't.
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 a guy tells his friends that his girlfriend is quality, he means that she is a great girlfriend.
When a guy tells you he feels a pit in his chest, he means that he has a chest pain.
She does not like him
Ejaculation
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.
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 Means he want to be your boyfriend!
That he likes you?
that you look good.
