idk if I did the right thing.

So my sexual partner and I had unprotected sex. Well needless to say I got plan b cause I got freaked out thinking he possibly came inside me and well He says it's his choice too and I should have asked him before I did that. Did I do the right thing by taking it or should I have asked him first. I'm so confused. If it means anything I did ask him to wear a condom and he said don't worry about it you'll be fine.
