wtf even is a kiss

this is kind of embarrassing but wTF do you do when you're kissing someone yes yes i know my lips touch his and our tongues dance in some weird way but SERIOUSLY WHAT DO I DO WITH MY TONGUE ? HOW AM I SUPPOSED TO MOVE IT ? TOUCH HIS , BLAH BLAH ALL THE VERY EXTREMELY DEEP DETAILS ? I really have no idea what people do when they put their tongues in each others mouth , and when they make that lil smooch noise?? when i was younger i always assumed they were just sucking on each others lip but noooo theres way more ? honestly i would really appreciate somebody giving me VERY explicit details on what the hell happens during a kiss
