Honestly, if your worried about it just mimick what your partner is doing because the kissing styles of each person varies. Therefore there is no one way to 'french kiss' so to speak. There is of course the known technique but sometimes people put a spin on it themselves. If you want a general idea, as lame as it sounds im sure youtube has a how to general guide or some tips if you're still worried. Hope this helps.

Don't shave or bathe for two weeks to get the full "French" effect.
Then just give your partner a big, slobber-filled smooch.

You'd have to be France first

Scrub your tongue first.

Just don't do as you suck lolipop or don't use your tongue. Make it long and simple kiss and don't forgot to take a big breath while doing it. Good Luck

Practice.
