Having sex for the first time ๐Ÿ˜๐Ÿ˜

I'm really excited, I recently got back together with my boyfriend after a break, and we're planning to have sex soon (were both virgins). I'm really excited, we've both been waiting ages to do this. we've both gotten everything sorted out, I've started going on the pill, he bought condoms, found somewhere comfy to do it etcetera. but there's a teeny problem, or, well really it's a big problem ๐Ÿ˜ณ I'm very tiny, everywhere, I'm short, I have small feet and hands, even down there is a little, well... but where the... problem comes in is that my boyfriend is seriously huge, and I'm not just talking about height. Do any other tiny women have any tips on how the hell to have sex with a dude that's 8 inches?? Like any tips on how to prep yourself, good lube for it etc?? please help!
