first boyfriend

ive never done anything (kissing, hooking up, any of that) and im seeing this guy, we are both going to this big party coming up and im planning to hook up with him (hooking up where im from is just kissing with tongue btw nothing more) and i dont know how to orchestrate it like do i bring him off to the side and then talk to him or do i just go in for it idk. also does anyone have any tips. im up for more like giving him hickeys and stuff but im just nervous and stuck.
