how do i try to pile if somebody wants to be fwb?

idk if pile is the right word but i mean like getting his stance or hinting at it or like with fishing using lead to pile the depth

so i have a friend know each other for a few months rn and recently hang out at my place nothing romantic but id gues id as here

we were there from 1.30pm till 11.30pm and its the first friend i have in a long time and hes a biological female if u get what i mean and i do view him with as a male but idk and it was the first time we actually were in private instead of a social location lets call it (we both dont have school)

probally because im a teen and hes a bit older (not saying specific ages but were both between 15 and 19 yes i know its weird but im a teen and will ignore the probally good advice of other people saying not to do it so dont even try like most teens i will just ignore it probally)

and were pretty open about sex like i never had sex or close to it well he did but like only dry and just some weird sex related questions like id ask wouldnt it hurt to put one of those giant dildos up your vagina and hed say probally i also dont get it and vice versa and general weird stuff but thats just our vibe

like id still be content if i or he never ends up asking and were just friends but with him it can go both ways tbh

sorry if it aint allowed here
