Need advise

So I know I'm only 16 almost 17 but I honestly truly  think I found the one.  I've felt this way ever since I started dating my bf I can actually imagine my life in the future with him.  I've been in love before but this time it's different anyways I've known him for a few years but we started dating only 5 months ago.  I am a virgin and I think I may be ready the only thing holding me back is that we've been dating only 5  montes and I'm terrified of getting pregnant I guess I just need advise on the whole sex thing and please no judgment I know I'm young
