Question...

Okay so, I’ve been with my boyfriend for almost 2 years now. Things are starting to get pretty serious and we’re starting to talk about the future (you know the run around). We have never had a fight, a few dumb arguments that were playful but not a true argument. We have been talking about becoming (active) if yk what I mean. But I’m a bit nervous to do it. It’s not that I’m not ready, k want to because o feel ready but I’m scared of the condom breaks. What should I do? Cause I have no clue how to go about this. (For reference we are both juniors now in high school.)
