well, first of all, you have to make absolutely sure you are both about to, or willing to, engage in a kiss. Otherwise the attempt will get awkward. After that, just bring your face and lips closer to the face of the one you are kissing and try to do what feels comfortable.
I'm not entirely sure what you're asking. Are you wanting us to try to teach you how to kiss someone? Or do you just want it defined? Either way, I'm not sure how satisfying our answers could possibly be, a forum isn't exactly where you'd go to learn how to kiss another person I wouldn't think.
You might have a look at this: How to kiss | Go Ask Alice! I would disregard the hint with the soap opera scenes... this is exaggerated stuff... I'd say this is like swimming... a bit of theory should suffice... just try it and keep at it... you might start with a kiss on the upper or lower lip and sucking gently on it... just take your time... when your time comes it will be ok
You just kind of stab the other person with your mouth, then 9 months later, babies pop out. Wait... I don't think this is quite right.
I think the most important thing is you have to genuinely be attracted to the person and vice versa. Other than that I'd just say dont overthink it. Making out is spontaneous and there isnt any code on how to do it right or anything. You pretty much just turn your brain off and do whatever feels right.
This is the type of thing where guides are not going to help, you just have to try it. Maybe you won't be great at it at first, with practice it'll go better. And too much tongue is never a good idea.
