i like what ms. pad said, there's no need for any technique and its just happended.
and like what ms. banana cake said, you will learn it when you get there and you'll learn more if you do it often
just one thing to consider,,,
if you kiss someone, please avoid staring, coz its not good watching your kiss partner while you two were kissing. it's very annoying... i believe that a lot of girls close their eyes during this kissing sessions but most guys love to stare at thier partner while doing it.
its a bad habbit... please avoid those.
