Amount of sperm after sex...

TTC
Hi ladies, I apologize for the nasty subject line. My DH and I are trying to conceive. Typically after we have sex there is a lot of left over sperm that leeks out immediately. Last nice there was none. This seems a little weird to me.  The last time we did it was 2 nights before. I asked him if he came and he told me yes. Could there be an explanation? Is this common with others and just a first for me?
