His dick is too big

I’ve (F20) been seeing this guy for a minute and we started hooking up a month into dating, I’m literally in love with him but when we sleep together my pelvic floor feels like it’s getting stabbed which makes it hard for me to fully enjoy his 8 inch dick. Like when he goes all the way in it feels the best but also the worst.

I think I just need tips on foreplay because during he’s always focused on me and asks what feels good and works for me. He says it doesn’t matter what I do for him and he doesn’t want me to worry about making him finish or anything, but he’s only had sex one time before me so I have a lot to teach him but overall he’s pretty good, lasts a LONG time, and is the only guy that I actually felt close to finishing with. He’s like a unicorn.

We’re always rushing due to circumstance but hopefully we can find a time (preferably a whole day) to explore and stuff.

We’ve figured out a little bit that when he like- fucks me fast and shallow I feel pure bliss and like I’m about to finish but he does RIGHT before me in that same way so idk bruh.

There’s a lot to tackle but he’s so patient with me and stops at every sign of discomfort so I just need some tips. We already communicate so much but I also haven’t had sex often in my life and so it’s a bit hard for me to know what it is I’d want from him too.
