If he looks into your eyes and bites his lip, he wants to kiss you...if he looks away he's too shy and wants you to make the first move. I agree with the answer above but they could also lean forward and have a slight pucker.
she starts looking at your lips
you can tell by the look in there eyes and the sound of there vocie
because your jealous, and he wants you to know, that he knows...your watching, or they just kissed :-)
dunno i never kissed anyone im in the 5th grade
Uhm, maybe she licks her lips alott. Or she is always looking at your lips.
Ask him.
Ask her out and see but you shoud not kiss your sister's friend.
If a girl doesn't like to be kissed then you don't kiss her. If she wants to kiss you she will.
He just wants some
when a guy wants to be kissed it will be pretty obvious. he will find any reason to touch you.. he may even play with your hair. if your standing close to each other looking into eachothers eyes, and he wants to kiss you, he will most likely be taking glimpses at your lips. if hes hugging you or holding your hand, hes trying to give you hints that hes interested. when the personal space boundary is invaded, he wants to kiss you.
start off by asking her if she has ever kissed a boy before?(if she replies no,ask her would she like for you to be her first?)
Sometimes it's just better not to try. Get to know her first. See how she reacts to you. If she wants to be kissed, she will let you know (sometimes in subtle ways).
