Question for you ladies, if you can help

Hey Ladies,

My hubby and I are TTC and last night we had sex and he hit something he never hit before and it was very sensitive. It didn't hurt or anything but just the feeling made body want to run away haha if that makes any sense. I'm not quite sure if it was my cervix he hit or what but whatever it was I hope it will help us with our baby making. Has anyone have a clue as to what it could of been to be so sensitive?
