How to initiate consensual and respectful first French kiss?

(17m) and my girlfriend (16f) are hanging out all day tomorrow she has already said that she would be comfortable trying French kissing, and more prolonged neck and cheek kissing, etc. we both were eachtohers first kiss around a month ago and I am meeting her parents after we watch the sunset at the beach. She is obviously very nervous because we have never French kissed before and it apparently takes some getting used to and isn’t to everyone’s taste (pardon the pun lol). My main concern is how exactly do you initiate it while still making it consensual and feeling natural? And then how the fuck do you do it lol? Do you just kiss a little wider than normal and ‘play’ with eachtohers tongue?

Pray for me
