stories abt ur first time and advice

I wanna have sex with my boyfriend and like we're not strangers to trying things like he's eaten me out/ fingered me n stuff and I've given him handjobs and blowjobs before. And I've never had a boyfriend before and I've only dated one other person my ex girlfriend (I'm bi) and she and I never rly tried anything big. So he's really my first everything and Im nervous abt having sex like our one year aniversery passed and we did things but like he's never put it inside of me so idk what to expect. Like all my friends say that fingering and getting eaten out don't compare to actually like having a dick inside of u but I'm just scared I'll be let down and idk what to expect. Anyone have any stories of ur  first time that you wanna share ? Also any advice ? Like I'm worried that I'll have to fake it and that I won't like it :/ what do I expect like does it hurt like everyone says ??
