Is this normal??!

So tonight I had sex for only like 3 min with my boyfriend. I stopped cuz I freaked out when I saw white stuff on the condom which he said it was from my vagina and I believe him cuz I’ve seen that white substance stuff before. I just don’t understand what that white stuff is tho. I know it can’t be his cum since he did not ejaculate and plus the condom was on properly with no holes. And also right before we had the sex I finished from him eating me out and didn’t wipe my fluids off after. So would that be what it’s from or is it from the friction combined with the lube that created a white fluid from my vagina? Has this happened to anyone else? Please lmk I’m panicking over this
