Weird sex thing tmi

Mo
So my bf and I had sex today and we use withdrawl method. He ejaculated on my back (we were in doggy) and wiped it all off and so I kneeled and all of a sudden there was like a while bunch below me that wasn't there before. Like it dropped from somewhere.... Ew. Hahah and please don't think I'm doing this to be like "oh my god am I pregnant!?!" But like has this happened to anyone else? Lol I'm just weirded out right now. That's never happened before 😂😂
