Why did this happen and is it normal?

I’ve NEVER had this happen EVER! But last night during sex it was foamy. Like, it looked like I put cool whip on his dick and inside me. No pain, no smell just white foamy discharge(like cool whip?) is that normal?? no issues after wiping it. But it’s super embarrassing. This a new experience and there’s no issues down there this morning! But it was literally the consistency of hair mousse.... it was also very slippery.
