please help me

hello, uneducated teenager here. there’s this boy that i’ve been talking to and he wants to have sex with me. what should i expect? im so nervous. is it going to hurt? do i need to do anything to myself to prepare? do you really need lube? do i need to bring a condom or is that his job? how can i wash properly so that i know it wont smell or taste bad? please just give me the basics so i can be ready😩

edit: i do want to have sex with him im just nervous and i feel unprepared
