Vaginal clumps?!

Ok so SOMEONE PLEASE EXPLAIN THIS it's a little gross in the story but I so need to know. He was fingering me and I sucked his finger (never done it) and there was this one single sort of clump, not solid like it dissolved I guess but I was just wondering what this is?? Is it normal? My discharge isn't clumpy and cottage cheesy it's not an infection I was just curious? thank you someone please explain
