first time pain?

my bf and i have been together a little over a yr now (both virgins and i'm his first gf). we've been talking a lot about "taking that next step" and we both believe that we're ready physically, mentally and emotionally, and we have protection. only thing i'm worried about is the pain..i know some girls experience no pain at all, some have a little pain but then it goes away after a bit, and some have pain throughout the whole first time..is there a way to know ahead of time which i'd be experiencing..? or at least, r there ways to lessen the pain before hand or maybe during..? (also, r these stupid questions..?)
