Help! I need advice!

So I'm 15, and I'm very very comfortable with my boyfriend. We've done some sexual things. For example; he's fingered me, and I've given him handjobs and stuff. So the thing is, we're super close and we both feel ready enough to have actual sex. And I have protection. But I'm worried that the condom would break or something. I know I'm 100% ready. I know we can be responsible about it, but even after doing research I feel like I need to know that we'll be totally safe with just using a condom. I always say that it really doesn't matter how young or old you are when you lose it because it's no one else's business but your own. But if anyone has any advice or wisdom, please share it!
