Fuck buddy tips?

So ive finally got someone that ive really wanted to have sex with to be my fuck buddy. Hes alot taller and skinnier than me. He refers me as a “stupid dumb thicc” so that means i hve a very big ass and 3 rolls and a fupa(fat upper pussy area) i am very insecure as to what to do since its my first time having a fuck buddy and what tips and tricks do you recommend me

And also how do i get my vagina to be smooth and not bumpy or pricky
