Come for me 😉

As
I have an ooddddd question. Since we've been TTC I've noticed that whenever my husband comes in me that it seems to spit out a few minutes after. Is this normal?? The first time it happened my husband laughed and I was like wth just happened? I mean isn't it supposed to (obviously) stay inside or is there something I can do to keep it inside? It's only been a few months since we've been TTC but I'm a little worried. Thanks tho and sorry for the odd description.
