Husband hit a wal??

So I’m 33.5weeks with baby number for and have never had pain during pregnancies or husband say anything felt different during sex.

Well the last few times I’ve notice some extra tenderness for me which I know can be normal with all the changes and blood flow down there. But as husband was finishing he said it felt like he “hit a wall” and it hurt a little for me..could it be my cervix..could that mean anything.. just curious if anyone has experienced this or what y’all think.
