my boyfriend and I have used condoms every single time we've had sex, but a week and a half ago we had a condom slip off inside me. he hadn't yet ejaculated and we immediately got the condom out and switched to a new one before continuing. then, the next morning, i found a random piece of latex in my bed. he said it was fine bc it didn't look like the kind we use, it was too thick, but why else would I have latex in my bed??? so I took the morning after pill (plan B one step) the next day just to make sure we'd be safe.
