how do you wait

So.. I'm waiting for birth control before I have sex. (I'm also waiting for condoms but still, I'm waiting) I'm 16 and I've been dating my boyfriend for over a year, it's been innocent up until a few months ago, and we've only done oral.. until a week ago when he tried to have sex but it didn't fit (I was wet so it wasn't that..) but now I'm freaking out because I really really want to- but I NEED to wait. Is there any way you guys made it easier for when you waited? I know a lot of people on her waited until marriage and I just need tips on how to make it less... painful(I don't lnow any other way to discribe it..
