First Time Nerves

So my boyfriend and I have been together for almost a year and our anniversary is coming up on July 24th. He has been very good to me about staying patient for sex because of my past when I was sexually assaulted by my ex a couple of years ago. He has not asked me for anything, and I mean NOTHING (no bj’s, handys, nothing). He’s been so good. Last week he came over and for the first time, he saw me naked and we did things..and for some strange reason it didn’t feel weird. In fact, it felt natural. Today I told him that I want our anniversary to be the night we do it, but I know that I’m going to be super nervous the night that it happens. I love and trust this guy with all my heart and want to make my first time special. Any tips on how to make myself less nervous and/or prepare for it?
