A French kiss should be done with a partially opened mouth, lips soft. Meet her lips, and then insert you tongue softly, if she responds with an open mouth as well. Your tongue should be soft and flexible, not rigid. This is to be sensual, not forceful...keep it soft. Move your soft tongue around in her mouth and against her tongue. Take you cues from her, as to when she wants the kiss to end. To end the kiss, you simply slowly withdraw your tongue, and close your mouth (not abruptly) with your lips still connected, and then pull apart, or go for another one.





I hope this helps.





EDIT:


You should also be softly embracing her during the kiss.





EDIT again:


Since you are shorter than her, you might have to embrace her so that you can level that off, and keep your chin up, of course.Help i need some first kiss advice asap?
It you are nervous about kissing her, then u are not really.
Just lock lips, hug her and move into it. Lock eyes, then move in. I happens naturally, trust me. I was worried too, it all turned out good..


(except for the fact that he had just broken up with my friend, whos not really my friend anymore.)
Two things: Be yourself and don't show that your nervous on the outside. Be confident.
aww thats so sweet little boy go for it kid dont even THINK about it if she likes you it will all go smoothly be carefull not to go TOO far though thats when it all goes downhill....
