Chunky-ish cum?

I don't even really know how to explain this. My cum recently has been kind of thick with like pieces that look almost like super tiny pieces of tampon or toilet paper in it and it will come off on my bfs dick. I've never noticed that before with any of my other boyfriends. I talked to my doctor and she wasn't even sure so she gave my yeast infection pills, but I'm almost positive I don't have a yeast infection because I don't have any of the normal symptoms. So I'm wondering if any one else's cum is like this or if anyone knows what it could be. I do try to wipe carefully so no toilet paper gets stuck to me, so I really don't think it's that either. Any thoughts??
