Prepping to lose my V

So next weekend my boyfriends parents are out of town and he wants me to stay the weekend and thinks it would be a good time for us to know each other intimately. I have no shame in saying that i am 20 and a virgin and he's 22 and not a virgin. But I will be honest I don't know what to do! He has experience he's told me he's slept with 4 girls. So I'm nervous because I've never done it. Of course we will use protection and he's made it super clear that we are taking our time and not rushing and if I'm uncomfortable with anything he'll stop or whatever.

Any tips or advice? I'd appreciate it!
