Might lose my virginity next weekend, any tips?

I’m quite nervous, i’ve never had anything in my vagina before (no tampons, no fingers, nothing. i’ve tried tampons before but I can never put them in right and they hurt). but I want to lose my virginity to my boyfriend next weekend. we are both virgins so i’m also afraid he won’t be able to find my hole lol. I know it sounds like we are young or something, but we are both actually 18. kind of embarrassing, I know.
