Beginner Advice!?

Hi! so i really need some advice

I'm 18 and I've literally never done anything sexual with a guy (never kissed or even held hands lol). Anyway, I'm on tinder and I've matched and have talked to a few guys that seem really cool and I know they probably only wanna have sex and I'm not ready to go that far yet.

But my question is, if you were a newbie at sex and everything related, how would you get started? I honestly want to get kissing out of the way but do I tell a guy that I've never done it? My friend says it'll be cute and they can like teach me but I kinda think its lame.
