WHY WAS HIS CUM LIKE THAT

My mans and I did it 5 times yesterday and he came each round, then the next morning we did it again but he didnt cum then 2nd time came around and his cum wasn't sperm like it was like water? not water but it shooted out like sperm but it wasnt white or creamy it was the texture if pee/water not a lot tho about the same amount as sperm, has this happened to anyone?
