First time sex

Had my first sex after doing some research. We used condom and he didn't finish cause i couldn't handle it much longer. After doing the deed, i tried filling the condom with water and i think it didn't leak and i think it was filled with precum. I don't have to take morning after pill don't i? I don't have anyone to rely on hence this post was made. Since i was born at some place where boomers thought sex ed = porn so i was lack with this kind of sense. I was a bit anxious and i do need some reassurance :")
