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

so i mean piling as in knowing how he thinks about it like when ur fishing and using lead to find the depth

so were both teens between 15-19 and i have a friend my only friend and i know him for 2-3 months rn we both dont go to school but a place to get a ryhtm and eventually get back to school or work

hes my only friend and recently first time u know just hanged out to gether privatley and it was fun it was from from like 12 pm as in midday to midnight at my place and it was really fun got some fries watched movies and just talking and we are really open together

like we had random conversations (he is a bilogical female) with things i asked woudlnt it hurt to put one of this giant dildo up your vagina he said yes and vice versa just really open and were still both virgins (he kinda is im fully) and just really open about sex etc

but idk im a horny teen and i mean sex like u get what i mean and hes the type that would probally unironically say yes to some weirdshit

sorry if this doesnt make sense and i dozed off im tired even after 2 cups off coffee and english aint my native

and i know fwb is probally a bad idea but im a teen and will ignore all of the probally proper advice that says dont do it
