M18 first time

so ive been w this girl for like 2 months now.

we hung out multiple times had dates this and that. Had sleepovers, and those got into makout sesh`s so basically we are getting close to having sex the problem that lies is, neither of us had our first times yet. We dont know what were doing. And i dont know if i should make the first move or not. Also last time we had a sleepover we had a makeout session. her hand went towards my pants slowly but then she just stopped and was like: i have no idea what i should do.

and i was like: yeah me too.

that was a lil cringe ngl. we stopped after that for like 3 min.

and i know that she also wants to have sex w me because everytime we makeout n shi she gets like i wouldnt say ultra wet but wet horny i would say. and is i dont know if i would call it that but humping my leg or groin.

so the question is should i talk with her about having sex,

wing it,

dont do it,

wait for her to make the first move ?

pls help
