Losing my virginity

Hey guys . So there's a guy I've been seeing for a while . And it's to the point where I know I am probably going to give up my virginity to him . I'm so scared though lol. yeah I know but all the mechanics, the blood and shit, the pain which scares me as well lol . but what I'm most scared about is that something's going to go wrong.  I don't know I'm just freaking out what if the condom breaks , I'm not on birth control yet and probably won't be able to get on it for a while ...Any tips to calm me down lol
