TMI, is this normal?

So I’m 38+3 and I very rarely have the energy to be sexual with my fiancé. Tonight was different so I took advantage of it. Being “in the mood,” he was using his fingers on me and it was really uncomfortable. It was like pressure when he went in, even a little, I had to ask him to stop using them because it was so uncomfortable. He also was a bit freaked out because there was a lot of what looked like clear discharge. He commented on how there was a lot more than ever before. He called it mucus, but it didn’t look like it so I shrugged it off. I’m assuming this is all normal, but I don’t think I’ll be attempting this again 😣
