I really need tips and techniques on how to kiss a boy urgently!?

Grab his balls.

Stop right there
You're asking for tips and techniques which means you're going to be over thinking it which what will make it bad.
Just go with the flow.

i agree. go with the flow, just dint think about it too much. make sure not to use your tongue on just a simple kiss and of course that your lips are soft and your breath is good you can also go ogle kissing tips just to keep in mind. but otherwise, just let it happen and smile

look him straight in the eyes, then look at his lips, then look back at his eyes and smile. he should get the hint. go slow, dint pucker up your lips and just relax. wrap your arms around his neck or rest your hands on his hips. after you re done, smile and grab his hand cutely. use mints and lip balm before you kiss him, NOT lip gloss or lip stick. just relax and have fun, hope this helps!
