Break What Makes A Condom Break? Is There A Specific Reason For It To Break During Sex Or Is It Just Bad Luck?

What makes a condom break? Is there a specific reason for it to break during sex or is it just bad luck? - break

Over the past two weeks, the condom broke twice (twice) and wants to know why cancel? What can I do to prevent a break? That has never happened to me or my friend before, but it has happened twice with us is ... I do not know if that has something to do, but it breaks when it comes up, but states that it is perfectly okay.

Please help me out!
