Did the condom break?

sooo my FWB and i had sex tonight, for the first time with him on top (usually i ride him, or we just do foreplay) that i am aware of, he’s never cum from me riding him, only head. usually he interrupts me riding him for head lol, then finishes. tonight, however, was the first time he finished inside of me. he had a condom on, but i felt the warmth of his cum? i almost feel like the condom broke, especially since asking my friends and them saying you don’t feel the cum, just their penis pulsating when they finish in you. i’m pretty new to sex, and already had a pregnancy scare with this FWB– my first sexual partner, for the record. we’re only 18, and both just working teen jobs and going to college, so a kid right now isn’t ideal. we’re also not together... can you guys offer reassurance, or should i go and get a plan b in the next 72 hours?

me currently googling only to find that you can’t feel it from various sources
